Bitcoin Price at Sep. 25, 2021: 42,694 USD

Investors are certainly reacting to news of China shutting down all crypto activity.

The "CNBC Television" Channel on Youtube shows that Jon Najarian joins the Halftime Report to discuss China's new crackdown on digital currencies. Bitcoin stock plunged after this morning's (Sep 24, 2021) announcement.

Bitcoin and Ether tumbled Friday, with traders concerned with tough talk out of China.

The price of bitcoin fell about 5% to $42,496.12 (Sep. 24, 2021), according to Coin Metrics data. Ether, the second-largest digital currency, dropped 7% to $2,921.53 (Sep. 24, 2021).

This price change comes after the People’s Bank of China said in a Q&A that all crypto-related activities are illegal. Services offering trading, order matching or derivatives for virtual currencies are strictly prohibited, the PBOC said, while overseas exchanges are also illegal.

Bitcoin Price at Sep. 25, 2021: 42,694 USD

Bitcoin Price at July 1, 2021 was: 33,204 USD

Major falls of the price have happened in the past as China imposed various restrictions on transactions involving cryptocurrencies.

The Bitcoin cryptocurrency fell from a "record high" of $64,895 USD hit on April 14.

Falls in Bitcoin price will certainly be a problem for people that are getting "Salaries in Bitcoin."

Some may think that Bitcoin could drop to 20K USD. Investors should be careful.

Canada has average of 2,200 people in hospital with COVID-19, about 700 in ICU

Global News in Canada shows that Canada's chief public health officer Dr. Theresa Tam said on Friday that the country is seeing a daily average of 2,200 people hospitalized due to COVID-19 and of those, about 700 are in intensive care units. She added that based on the 7-day average, 36 deaths a day due to COVID-19 infections.

And according to Canada's deputy chief public health officer Dr. Howard Njoo, the best way to protect children under the age of 12 who are not eligible to get the COVID-19 vaccine from getting sick and staying in school is for the adults around them to receive the shots.

The update comes as Alberta finds its hospitals pushed to the limits due to a surge in COVID-19 cases. The province has been in the national spotlight for weeks over its handling of the fourth wave, following a relaxation of protective measures in the summer.

The Canadian health update also follows the the USA authorizing booster shots of Pfizer’s COVID-19 vaccine for certain high-risk groups. 

Canada’s National Advisory Committee on Immunization (NACI) is still reviewing whether booster shots would be needed in the broader population.

Canadian Prairies struggle with crushing 4th wave of COVID-19

Global News in Canada shows that hospitals in Alberta overwhelmed with COVID-19 patients are changing the way they deliver care. The province is 1 crisis away from doctors having to make difficult decisions on issues like who gets a ventilator and who does not. Heather Yourex-West reports on how Calgary is responding swiftly through the use of mandatory vaccine passports.

Saskatchewan’s hospitals are also being crushed by the fourth wave, and adults are now filling pediatric ICUs. A record 273 are hospitalized with the virus and more than 75 per cent of them are not fully vaccinated. Nataniel Dove looks at the latest plea for everyone to get vaccinated.

The U.S. Food and Drug Administration (FDA) and an advisory panel for the Centers for Disease Control and Prevention (CDC) has largely approved booster shots for some Americans. But there's still a debate about whether the shots are necessary for the general public at a time when so many are still unvaccinated. Jackson Proskow explains who might be able to get a third dose soon.

Canada: Do COVID-19 vaccine mandates violate civil liberties?

CBC News in Canada shows that the head of the Canadian Civil Liberties Association, Michael Bryant, says what really matters are exceptions or accommodations built into the vaccine mandates. 'We have the rules and regulations released in Quebec and Manitoba. We don't have them yet in Ontario and B.C.'

Buyer beware: What is "shrinkflation" and how does it affect food prices?

Global News in Canada shows that "Shrinkflation" can be considered inflation's sneaky cousin, with the sticker price of the item staying the same but you're actually paying more for less product. 

According to food experts, the price of raw goods like meat, canola, wheat and corn are up and manufacturers manage that by either increasing prices or downsizing how much customers get.

As Anne Gaviola explains, it's become difficult for people to literally compare apples to apples and is not a simple calculation when making your budget.

Global News in Canada shows how Re-elected Prime Minister Justin Trudeau met with commuters at Jarry Metro Station in Montreal on Tuesday, after winning a minority government in Monday’s federal election.

Trudeau had billed the election, which he triggered on Aug. 15, as a chance for Canadians to choose which party’s vision for the COVID-19 recovery they most support over the coming years.

The Liberal leader will need to continue working with the other parties in order to govern and pass the major pieces of legislation he promised voters during the campaign.

Canada election: What's next for the newly-re-elected Trudeau minority government?

Global News in Canada shows that Liberal Leader Justin Trudeau has been re-elected as prime minister with a minority government, and the results were nearly identical to the 2019 federal election.

As for the other party leaders, speculations rise on whether they'll step down from their role - specifically Green Party Leader Annamie Paul, who came in fourth place in her riding of Toronto's Davenport riding. 

The PPC didn't win any seats, just like in 2019. 

Global's Sean O'Shea explains what's next following the 2021 federal election and what the new liberal minority means for Canadians.

Canadian federal election night in under 7 minutes

Global News in Canada shows that Liberal Leader Justin Trudeau is going hard in the final days of the federal election campaign, with seven stops in southern Ontario on Saturday. As Abigail Bimman reports, Trudeau is returning to ridings where the race to victory will be tight. 

Conservative Leader Erin O'Toole dodged questions about whether candidates in his party are vaccinated against COVID-19. As Mike Le Couteur explains, O'Toole’s lack of answers, and the urgency in the final days of the campaign, could lose him votes.

NDP Leader Jagmeet Singh is targeting the Conservative premiers of Alberta and Saskatchewan, two of Canada's COVID-19 hotspots, while campaigning in the Prairie provinces. As Robin Gill explains, Singh isn't just attacking those leaders' handling of the pandemic. 

Green Party Leader Annamie Paul has finally taken her campaign to British Columbia, where the party held its two remaining seats when Parliament was dissolved. But Paul's final pitch may not be enough to keep those seats from slipping away from the Greens. Richard Zussman reports from Victoria, B.C.

Funniest Animals - Cats and Dogs - Best Of 2021 Funny Animal Videos

Take a look at great funny animals: Funniest Animals - Cats and Dogs - Best Of 2021 Funny Animal Videos.

The so-called word "Humour" (Commonwealth English) or "humor" (American English) is the tendency of experiences to provoke laughter and provide amusement. The term derives from the humoral medicine of the ancient Greeks, which taught that the balance of fluids in the human body, known as humours (Latin: humor, "body fluid"), controlled human health and emotion.

People of all ages and cultures respond to funny humour. Most people are able to experience so-called humour - be amused, smile or laugh at something funny (such as a pun or joke) - and thus are considered to have a sense of humour. The hypothetical person lacking a sense of humour would likely find the behaviour inducing it to be inexplicable, strange, or even irrational. Though ultimately decided by personal taste, the extent to which a person finds something humorous depends on a host of variables, including geographical location, culture, maturity, level of education, intelligence and context. More sophisticated forms of humour exist such as satire. They require an understanding of its social meaning and context.

Funny Animals - Cute Dogs And Cats That Will Make You Laugh

Funny Animals' Life on Youtube shows you the funny animals.

Thanks for wonderful music by Vexento - "Digital Hug"

The so-called "dog" or "domestic dog" (Canis familiaris) is a domesticated descendant of the wolf, characterized by an upturning tail. The dog derived from an ancient, extinct wolf, and the modern grey wolf is the dog's nearest living relative. The dog was the first species to be domesticated, by so-called hunter-gatherers over 15,000 years ago, before the development of agriculture. Their long association with humans has led dogs to be uniquely adapted to human behavior, leading to a large number of domestic individuals and the ability to thrive on a starch-rich diet that would be inadequate for other canids.

The dog has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They perform many roles for humans, such as hunting, herding, pulling loads, protection, assisting police and the military, companionship, therapy, and aiding disabled people. This influence on human society has given them the sobriquet of so-called "man's best friend."

Synonyms of "sobriquet":


The so-called "cat" animal (Felis catus) is a domestic species of small carnivorous mammal. It is the only domesticated species in the family Felidae and is often referred to as the so-called domestic cat to distinguish it from the wild members of the family. A cat can either be a house cat, a farm cat or a feral cat; the latter ranges freely and avoids human contact. Domestic cats are valued by humans for companionship and their ability to hunt rodents. About 60 cat breeds are recognized by various cat registries.

The cat is similar in anatomy to the other felid species: it has a strong flexible body, quick reflexes, sharp teeth and retractable claws adapted to killing small prey. Its night vision and sense of smell are well developed. Cat communication includes vocalizations like loud or quiet meowing, purring, trilling, hissing, growling and grunting as well as cat-specific body language. A predator that is most active at dawn and dusk (crepuscular), the cat is a solitary hunter but a so-called social species. It can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small mammals. It secretes and perceives certain pheromones.

So You Got Science Of Funny Animals

Science Loop on Youtube has another interesting video: So You Got Science Of Funny Animals, ... Now What? [part 2]

See the Internet's most funny videos and their Scientific explanations. This is the Part 2 of this Series about how dolphins mimic using echolocation, why these animals follow points, the massive power of elephant trunks, and many more interesting animal science facts.

Don't Forget to watch Part 1:

1. Dog slipping on a surface
2. Dolphin
3. Point follow 
4. Massive power of elephant trunk

So-called "Cherophobia" is THE FEAR OF BEING HAPPY. Cherophobia is certainly a phobia where a person has an irrational aversion to being happy. The term comes from the Greek word "chero," which means "to rejoice." When a person experiences cherophobia, they're often afraid to participate in activities that many would characterize as fun, or of being happy.

See how dolphins mimic using echolocation, why these animals follow points, the massive power of elephant trunks, and much more.

"Echolocation" is an interesting effect. Nature's so-called own sonar system, echolocation occurs when an animal emits a sound wave that bounces off an object, returning an echo that provides information about the object's distance and size. Over a thousand species echolocate, including most bats, all toothed whales, and small mammals.

Dolphin communication is interesting. It seems that Dolphins Speak Body Language. Beyond echolocation, clicking and whistling, dolphins communicate with a variety of body language signals including tail and flipper slapping on water, leaping out of water, bumping each other and spy hopping.

Dolphin communication is certainly called "echolocation." Clicks are used to sense their surroundings through echolocation, while they use whistles to communicate with other members of their species and very likely, with certain other species too. It is also thought that each dolphin has a unique whistle called a 'signature whistle', which is used to identify an individual.

Dolphins certainly communicate using a vast array of sounds and nonverbal gestures. Like humans, dolphins use both verbal utterances and nonverbal gestures to communicate with one another. These include whistles, clicks, and loud broadband packets of sound called burst pulses.

It seems that smart dolphins demonstrate the ability to do intellegent things and most scientists agree that dolphins are very intelligent. They are notoriously talented mimics and quick learners; they demonstrate self-awareness, problem-solving, and empathy, innovation, teaching skills, grief, joy and playfulness.

Dolphins can bite. Dolphins certainly have sharp teeth that they usually use to rip apart their prey. Bottlenose dolphins, for example, have between 80 and 100 teeth that they use to grab, grip and secure their prey. The underwater creatures can also bite humans on occasion.

If a certain dolphin approaches you in the water, do not engage, follow, or otherwise interact with the animal. Allow it to pass by undisturbed and maintain its so-called natural animal behaviors.

Dolphins at swim-with attractions have been known to seriously attack and hurt humans by butting them and the resulting injuries have included lacerations and broken bones.

It seems that some friendly dolphins can save people from drowning.

Never touch or pet dolphins, even if they come close enough to touch. Use binoculars to watch dolphins from a safe distance in their so-called natural habitat, instead.

It seems that some dolphins "get high." A documentary shows dolphins in trance-like state after snacking on puffer fish. A new documentary on the BBC shows dolphins using pufferfish to get to a trance-like state.

SpaceX’s Mechazilla Is More Mind Blowing Than You Think!

Futurity on Youtube shows that once completed, the Mechazilla will enable SpaceX to launch the Starship up to three times a day so let’s find more about this secret weapon!

At Futurity, they scour the globe for all the latest tech releases, news and info just so you don't have to! Covering everything from cryptocurrency to robotics, small startups to multinational corporations like Tesla and Jeff Bezos to Elon Musk and everything in between!

Mechagodzilla (メカゴジラ, Mekagojira) is a fictional mecha character that first appeared in the 1974 film Godzilla vs. Mechagodzilla. In its debut appearance, Mechagodzilla is depicted as a certain extraterrestrial villain that confronts Godzilla. In subsequent iterations, Mechagodzilla is usually depicted as a man-made weapon designed to defend country of Japan from Godzilla. In all incarnations, the character is portrayed as a robotic doppelgänger with a vast array of powerful weaponry, and along with King Ghidorah, is commonly considered to be an archenemy of so-called Godzilla.

A doppelgänger is an apparition or double of a living person. For example, "he has been replaced by an evil doppelgänger."

Construction: Toronto: Yonge and Spring Garden - August 2021

There is some interesting construction going on at Yonge St & Spring Garden Ave in Toronto, ON, Canada. Interesting site plans and explanations of the construction can be found here:

Toronto is a densely populated city with many condos and cranes. All non-essential construction projects will be halted to help slow the spread of Coronavirus COVID-19. The list of exceptions under this category, however, is long and complicated. Allowed projects are "infrastructure projects such as new hospitals, roads and bridges" and "residential construction that is near completion." The rules also allow many of the condo projects and residential home renovations that have already started.

On April 16, 2021, in response to alarming new COVID-19 case growth and a third wave of the COVID-19 pandemic, the Ontario government announced a return to shut down of certain non-essential construction projects, with effect at 12:01 a.m. on Saturday, April 17, 2021. There is now the possibility of a 4th virus wave.

This Star Explosion Will Be Seen On The Earth in 2022, Can We Survive It?

A supernova is really the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of some star.

Massive stars really burn huge amounts of nuclear fuel at their cores, or centers. This produces tons of powerful energy, so the center gets very hot. Heat generates pressure, and the pressure created by a star’s nuclear burning also keeps that star from collapsing.

A star is in balance between 2 opposite forces. The star’s gravity tries to squeeze the star into the smallest, tightest ball possible. But the nuclear fuel burning in the star’s core creates strong outward pressure. This outward push resists the inward squeeze of gravity.

These fantastic spectacular space events can be so bright that they outshine their entire galaxies for a few days or even months. They can be seen across the universe.

If you are seeing a star explode in the sky, it might have actually exploded more than 13,000 years ago. Light travels at the speed of light.

The speed of light = 299 792 458 m / s

The so-called "speed of light" in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is defined as 299792458 metres per second (approximately 300000 km/s, or 186000 mi/s). It is exact because, by international agreement, a metre is defined as the length of the path travelled by light in vacuum during a time interval of 1⁄299792458 second. According to special relativity, c is the upper limit for the speed at which conventional matter, energy or any signal carrying information can travel through space.

10 LIES You Were Told About Space

Crunch on Youtube shows you the space story. Here are 10 lies you were told about space. Space myths like these are always corrected with space discoveries. Here are lies you believe about space, sometimes portrayed by NASA.

Other Planets - A Raindrop Is a Raindrop, Even When It’s Metal

SciShow Space on Youtube shows that on planet earth it rains water, on the exoplanet WASP-76b, it rains liquid iron. But, no matter what planet you're on, the rain drops there have a lot more in common than you might think.

The rain on other planets has very different chemical compositions. On Venus, it rains sulfuric acid. On Mars it snows dry ice, which is carbon dioxide in a solid state. Saturn's moon Titan rains methane, and on Jupiter, it rains helium and mushy ammonia hailstones.

It seems that there is indeed rain falling from clouds on other planets, but it's not water. According to the findings, diamond rain falls on Saturn, Neptune and Jupiter, among others, but Saturn might have the best conditions for it.

It seems that planet Earth is the "only planet" that has liquid water. There is indeed rain falling from clouds on other planets, but it's not water.

About 1,000 tons (907 metric tons) of diamonds a year fall on Saturn. It's still an unpublished theory. This is a theory by planetary scientists at the NASA Jet Propulsion Laboratory. It seems to be unproven.

Over on Titan, Saturn's largest moon, there are icy methane rainstorms. Just as Earth has a water cycle, Titan has a methane cycle. There are seasonal rains. The methane rain fills up lakes. The lakes eventually evaporate and the vapor ascends into the clouds, starting the whole thing over again. Methane is in its liquid form on Titan because the surface temperature is an extremely cold chilly minus 290 degrees F (minus 179 C). There are also cold solid-ice mountains on Titan.

Astronomers Discovered Strange Signs of Life on a Saturn moon

Crunch on Youtube shows that Astronomers Discovered Strange Signs of Life on a Saturn moon. Saturn's moons have always been of interest to scientists for many reasons.

Futurity Channel on Youtube shows the SpaceX technologies. Keep watching to find out more about how SpaceX Bakery manufactures the most important parts of their thermal protection systems - heat shield tiles! Subscribe to Futurity for more SpaceX news.

It is interesting: what is SpaceX heat shield made of. The spacecraft's eventual heatshield will be composed of many so-called "hex tiles", hexagonally shaped bits of ceramic shielding designed to dissipate the enormous amounts of hot heat generated during reentry into the Earth's atmosphere.

A Starship would have many heat tiles. There were 20,548 HRSI tiles which covered the landing gear doors, external tank umbilical connection doors, and the rest of the orbiter's under surfaces.

SpaceX certainly does have a useful heat shield. As it prepares for its second human spaceflight mission next month, SpaceX company has redesigned a small portion of its spacecraft's heat shield in addition to making a few other refinements to the Dragon capsule.

The black tiles on the Starship are interesting. The fascinating tiles exposed to reentry temperatures of up to 2,300 degrees Fahrenheit, such as those on portions of the belly, are given a protective coating of certain black glass. Black tiles work by reflecting an amazing about 90 percent of the heat they're exposed to back into the atmosphere, while the tiles' interior absorbs the rest.

The useful SpaceX heat shield works in interesting ways. The shield protects Crew Dragon by deflecting and absorbing heat that can reach 3,500 degrees Fahrenheit while the space capsule plummets through the atmosphere and creates superheated plasma on its return to Earth. "Wear and tear" happens to spaceships - this is an important thing to think about.

SpaceX has 2 interesting rocket test facilities for vertical takeoff, vertical landing rockets: the SpaceX Rocket Development and Test Facility in McGregor, Texas and a leased test facility at Spaceport America in southern New Mexico.

SpaceX seems to trade on the stock market. The shares trade on the London Stock Exchange. The first of these investment trusts, Scottish Mortgage Investment Trust, has a 0.8% exposure in SpaceX as part of its ticker symbol SMT.

It seems that Google owns some of SpaceX. In January 2015, SpaceX raised US$1 billion in funding from Google and Fidelity, in exchange for 8.33% of the company, establishing the company valuation at approximately US$12 billion.

SpaceX rockets use various fuels. SpaceX's next-generation Raptor engine, which will power the company's huge new Starship deep-space transportation system, employs supercooled liquid methane and LOX as propellants. The company's previous engines, Merlin and Kestrel, have also used LOX, though with refined kerosene rather than methane.

(From Feb. 17, 2021) SpaceX raises $850 million at Elon Musk's favorite price of $420 per share. Elon Musk, Tesla's CEO, owns SpaceX. Elon Musk's SpaceX is now valued at about $74 billion, CNBC reported. The aerospace company raised $1.9 billion in August to help fund its Starlink and Starship projects.

It seems that Musk is still the largest shareholder and the CEO of SpaceX, and the large company is now worth far more than the $100 million that Musk originally invested to form the company.

It seems that the highest paying job at SpaceX is "Senior Software Engineer." The highest-paying job at SpaceX is a Senior Software Engineer with a salary of $247,959 per year.

What The Next Space Station May Look Like

CNBC shows that the International Space Station will likely be retired within the decade. NASA hopes to save money by having commercial companies build the next space outpost. Some companies including Sierra Space and Axiom Space are already working on a commercial space station. But the question is, will these stations be ready in time?

The Biggest Comet Ever Found is Headed Our Way

"SciShow Space" on Youtube shows you that expert scientists are discovering new objects in the solar system all the time. Most of these are small asteroids or icy bodies, but researchers recently spotted something unexpectedly huge heading our way.

A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have certainly been observed and recorded since ancient times by many cultures and religions.

Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several millions of years. Short-period comets originate in the Kuiper belt or its associated scattered disc, which lie beyond the orbit of Neptune. Long-period comets are thought to originate in the Oort cloud, a spherical cloud of icy bodies extending from outside the Kuiper belt to halfway to the nearest star. Long-period comets are set in motion towards the Sun from the Oort cloud by gravitational perturbations caused by passing stars and the galactic tide. Hyperbolic comets may pass once through the inner Solar System before being flung to interstellar space. The appearance of a comet is called an apparition.

Comets are certainly distinguished from asteroids by the presence of an extended, gravitationally unbound atmosphere surrounding their central nucleus.

Astronews Recent Space Discoveries (Mars Orbiter Finds, Dangerous asteroids, Alma Telescope & More)

"Insane Curiosity" on Youtube shows you interesting space news. Welcome to the thirteenth astronews of "Space and Astronomy" news, selected for you by Insane Curiosity Channel. See Space News and other cool news.

Space is certainly the so-called boundless three-dimensional extent in which various objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless 4-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a so-called conceptual framework.

Cherenkov Effect: Technically it is Faster than Light

The Science Loop Channel on Youtube has another interesting science video for you. It is about the Cherenkov Effect.

Technically, this is a photonic boom. Don't get excited here! This is called the Cherenkov effect. When a charged particle goes faster than the speed of light in a medium it creates this gorgeous blue light. In a medium Light travel a little bit slower than the vacuum. So other particles can go faster without violating relativity.

Particle physics (also known as high energy physics) is really a branch of physics that studies the nature of the particles that constitute matter and radiation.

The Cherenkov effect occurs when a particle carrying an electric charge travels through a transparent medium like water or air. If the particle travels faster than light in this medium, its passage causes a brief flash of light, a Cherenkov light. Very high speeds are impressive.

Cherenkov (Russian: Черенков) radiation  is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity (speed of propagation of a wave in a medium) of light in that medium. Special relativity is not violated since light travels slower in materials with refractive index greater than one, and it is the speed of light in vacuum which cannot be exceeded (or reached) by particles with mass. A classic example of Cherenkov radiation is really the characteristic blue glow of an underwater nuclear reactor. Its cause is similar to the cause of a sonic boom, the sharp sound heard when faster-than-sound movement occurs. The phenomenon is named for Soviet physicist Pavel Cherenkov, who shared the 1958 Nobel Prize in Physics for its discovery.

The so-called Frank-Tamm formula yields the amount of Cherenkov radiation emitted on a given frequency as a charged particle moves through a medium at superluminal velocity. It is named for Russian physicists Ilya Frank and Igor Tamm who developed the theory of the Cherenkov effect in 1937, for which they were awarded a Nobel Prize in Physics in 1958.

When a so-called charged particle moves faster than the phase speed of light in a medium, electrons interacting with the particle can emit coherent photons while conserving energy and momentum. This process can be viewed as a decay. See Cherenkov radiation and nonradiation condition for an explanation of this effect.

The History of Radiation Discoveries is interesting. This is really one of various effects of radiation. This radiation effect is named after the Soviet scientist Pavel Cherenkov, the 1958 Nobel Prize winner, who was the first to detect it experimentally under the supervision of Sergey Vavilov at the Lebedev Institute in 1934. Therefore, it is also known as Vavilov-Cherenkov radiation. Cherenkov saw a faint bluish light around a radioactive preparation in water during experiments. His doctorate thesis was on luminescence of uranium salt solutions that were excited by gamma rays instead of less energetic visible light, as done commonly. He discovered the anisotropy of the radiation and came to the conclusion that the bluish glow was not a fluorescent phenomenon.

"Fluorescence" is the ability of certain chemicals to give off visible light after absorbing radiation which is not normally visible, such as ultraviolet light.

"Anisotropy" is the property of being directionally dependent, as opposed to isotropy, which means homogeneity in all directions. It can be defined as a difference in the physical property of a certain material when measured along different axes. Anisotropy in ultrasound examination is an angle-generated artifact.

Cherenkov Effect: a theory of this certain effect was later developed in 1937 within the framework of Einstein's special relativity theory by Cherenkov's colleagues Igor Tamm and Ilya Frank, who also shared the 1958 Nobel Prize.

Cherenkov radiation as conical wave front had been theoretically predicted by the English polymath Oliver Heaviside in papers published between 1888 and 1889 and by Arnold Sommerfeld in 1904, but both had been quickly forgotten following the relativity theory's restriction of super-c particles until the 1970s. Marie Curie observed a pale blue light in a highly concentrated radium solution in 1910, but did not investigate its source. In 1926, the French radiotherapist Lucien Mallet described the luminous radiation of radium irradiating water having a continuous spectrum.

In 2019, a team of researchers from Dartmouth’s and Dartmouth-Hitchcock's Norris Cotton Cancer Center discovered Cherenkov light being generated in the vitreous humor of patients undergoing radiotherapy. The light was observed using a camera imaging system called a CDose, which is specially designed to view light emissions from biological systems. For decades, patients had reported phenomena such as "flashes of bright or blue light" when receiving radiation treatments for brain cancer, but the effects had never been experimentally observed.

There is also something called "Reverse Cherenkov effect." A reverse Cherenkov effect can be experienced using materials called negative-index metamaterials (materials with a subwavelength microstructure that gives them an effective "average" property very different from their constituent materials, in this case having negative permittivity and negative permeability). This means that, when a charged particle (usually electrons) passes through a medium at a speed greater than the phase velocity of light in that medium, that particle emits trailing radiation from its progress through the medium rather than in front of it (as is the case in normal materials with, both permittivity and permeability positive). One can also obtain such reverse-cone Cherenkov radiation in non-metamaterial periodic media where the periodic structure is on the same scale as the wavelength, so it cannot be treated as an effectively homogeneous metamaterial.

Cherenkov radiation has many uses, such as:

Detection of labelled biomolecules
Medical imaging of radioisotopes and external beam radiotherapy
Nuclear reactors
Cherenkov radiation in a TRIGA reactor pool
Astrophysics experiments
Particle physics experiments

There are 2 kinds of radiation: non-ionizing radiation and ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. Examples of this kind of radiation are radio waves, visible light and microwaves.

Radiation can also be put into these 7 types of radiation:

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

Radiation is energy that comes from a source and travels through space and may be able to penetrate various materials. Light, radio, and microwaves are types of radiation that are called nonionizing. Gamma radiation and x rays are examples of electromagnetic radiation.

Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (radiation sickness). It can also result in long-term health effects such as cancer and cardiovascular disease.

All modern communication systems use forms of electromagnetic radiation. Variations in the intensity of the radiation represent changes in the sound, pictures, or other information being transmitted. For example, a human voice can be sent as a radio wave or microwave by making the wave vary to corresponding variations in the voice. Musicians have also experimented with gamma rays sonification, or using nuclear radiation, to produce sound and music.

Researchers use radioactive atoms to determine the age of materials that were once part of a living organism. The age of such materials can be estimated by measuring the amount of radioactive carbon they contain in a process called radiocarbon dating. Similarly, using other radioactive elements, the age of rocks and other geological features (even some man-made objects) can be determined; this is called Radiometric dating. Environmental scientists use radioactive atoms, known as tracer atoms, to identify the pathways taken by pollutants through the environment.

Radiation is used to determine the composition of materials in a process called neutron activation analysis. In this process, scientists bombard a sample of a substance with particles called neutrons. Some of the atoms in the sample absorb neutrons and become radioactive. The scientists can identify the elements in the sample by studying the emitted radiation.

Some other Radiation Effects:

Askaryan Effect

Bremsstrahlung (from bremsen "to brake" and Strahlung "radiation"; i.e., "braking radiation" or "deceleration radiation")

Radioluminescence is the phenomenon by which light is produced in a material by bombardment with ionizing radiation such as alpha particles, beta particles, or gamma rays.

A tachyon or tachyonic particle is a hypothetical particle that always travels faster than light.

Transition Radiation (TR) is a form of electromagnetic radiation emitted when a charged particle passes through inhomogeneous media, such as a boundary between 2 certain different media. This is in contrast to Cherenkov radiation, which occurs when a charged particle passes through a homogeneous dielectric medium at a speed greater than the phase velocity of electromagnetic waves in that medium.
