Tim Blais
Tim Blais is a Canadian science communicator. He explains scientific topics via writing and performing a capella parodies of popular music which he records and posts on his YouTube channel, ''A Capella Science''. Early life and education Blais was born in Hudson, Quebec. Blais states that he comes from an "incredibly musical" family. His mother leads a church choir; Blais joined the choir when he was three. He also plays drums, piano, and stringed instruments including guitar. Blais graduated from McGill University in 2011 with a Bachelor of Science degree. In 2013, he earned a master's degree in high-energy theoretical physics with honors from McGill. Career Blais created his first parody video in 2012, motivated by a desire to help people understand the world around them. He states that creating parody videos with a factual science theme came out of being fascinated by science, music (particularly a capella), and parody. He was inspired by "Weird Al" Yankovic, Bill Nye, Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hudson, Quebec
Hudson is an off-island suburb of Montreal, with a population of 5,135 ( 2011 Census). It is located on the south-west bank of the lower Ottawa River, in Vaudreuil-Soulanges Regional County Municipality. Situated about west of downtown Montreal, many residents commute to work on the Island of Montreal. Hudson is a municipality within Greater Montreal. An informal rural agglomeration since the early part of the 19th century, the Town of Hudson was formally created in June 1969 by merging the villages of Hudson, Hudson Heights and Como. A relatively wealthy town, Hudson is known for its large, turn-of-the century houses, many of which border the Lake of Two Mountains. A ferry from Hudson takes cars across the lake (a widening of the Ottawa River) to the village of Oka. Hudson has been compared to culturally and demographically similar Quebec towns such as the Eastern Townships villages of North Hatley and Brome Lake as well as nearby Senneville. All four municipalities border ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Insulin
Insulin (, from Latin ''insula'', 'island') is a peptide hormone produced by beta cells of the pancreatic islets encoded in humans by the ''INS'' gene. It is considered to be the main anabolic hormone of the body. It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of glucose from the blood into liver, fat and skeletal muscle cells. In these tissues the absorbed glucose is converted into either glycogen via glycogenesis or fats (triglycerides) via lipogenesis, or, in the case of the liver, into both. Glucose production and secretion by the liver is strongly inhibited by high concentrations of insulin in the blood. Circulating insulin also affects the synthesis of proteins in a wide variety of tissues. It is therefore an anabolic hormone, promoting the conversion of small molecules in the blood into large molecules inside the cells. Low insulin levels in the blood have the opposite effect by promoting widespread catabolism, especially o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exoplanet
An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not recognized as such. The first confirmation of detection occurred in 1992. A different planet, initially detected in 1988, was confirmed in 2003. There are many methods of detecting exoplanets. Transit photometry and Doppler spectroscopy have found the most, but these methods suffer from a clear observational bias favoring the detection of planets near the star; thus, 85% of the exoplanets detected are inside the tidal locking zone. In several cases, multiple planets have been observed around a star. About 1 in 5 Sun-like starsFor the purpose of this 1 in 5 statistic, "Sun-like" means G-type star.

Entropy (arrow Of Time)
Entropy is one of the few quantities in the physical sciences that require a particular direction for time, sometimes called an arrow of time. As one goes "forward" in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease. Thus, entropy measurement is a way of distinguishing the past from the future. In thermodynamic systems that are not isolated, entropy can decrease with time, for example living systems where local entropy is reduced at the expense of an environmental increase (resulting in a net increase in entropy), the formation of typical crystals, the workings of a refrigerator and within living organisms. Much like temperature, despite being an abstract concept, everyone has an intuitive sense of the effects of entropy. For example, it is often very easy to tell the difference between a video being played forwards or backwards. A video may depict a wood fire that melts a nearby ice block, played in reverse it would show ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astrophysics
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. As one of the founders of the discipline said, Astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space–''what'' they are, rather than ''where'' they are." Among the subjects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. Emissions from these objects are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, ''astrophysicists'' apply concepts and methods from many disciplines of physics, including classical mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and m ...

Doctor Of Philosophy
A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin: or ') is the most common Academic degree, degree at the highest academic level awarded following a course of study. PhDs are awarded for programs across the whole breadth of academic fields. Because it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and defend their work before a panel of other experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title ''Doctor (title), Doctor'' (often abbreviated "Dr" or "Dr.") with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society.

Brian May
Brian Harold May (born 19 July 1947) is an English guitarist, singer, songwriter, and astrophysicist, who achieved worldwide fame as the lead guitarist of the rock band Queen (band), Queen. May was a co-founder of Queen with lead singer Freddie Mercury and drummer Roger Taylor (Queen drummer), Roger Taylor. His songwriting contributions helped Queen become among the most successful acts in music history. May previously performed with Taylor in the blues rock band Smile (band), Smile, which he had joined while he was at university. After Queen's formation in 1970, bass guitarist John Deacon joined to complete the line-up in 1971. They became one of the biggest rock bands in the world with the success of the album ''A Night at the Opera (Queen album), A Night at the Opera'' and its single "Bohemian Rhapsody". From the mid-1970s until the early 1990s, Queen played at some of the biggest venues in the world, including at Live Aid in 1985. As a member of Queen, May became regarded ...

Albert Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ' ...

Sock Puppet
A sock puppet or sockpuppet is a puppet made from a sock or a similar garment. The puppeteer wears the sock on a hand and lower arm as if it were a glove, with the puppet's mouth being formed by the region between the sock's heel and toe, and the puppeteer's thumb acting as the jaw. The arrangement of the fingers forms the shape of a mouth, which is sometimes padded with a hard piece of felt, often with a tongue glued inside. The sock is stretched out fully so that it is long enough to cover the puppeteer's wrist and part of the arm. Often, the puppeteer hides behind a stand and raises the hand above it so that only the puppet is visible. Sock puppeteers may also stand in full view along with their puppets and hold conversations with them through using ventriloquism. Composition Sock puppets can be made from socks or stockings of any color. Any sock may be used to create a puppet, but socks that are too tattered may fall apart during a performance, so they are usually bought n ...

String Theory
In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and interact with each other. On distance scales larger than the string scale, a string looks just like an ordinary particle, with its mass, charge, and other properties determined by the vibrational state of the string. In string theory, one of the many vibrational states of the string corresponds to the graviton, a quantum mechanical particle that carries the gravitational force. Thus, string theory is a theory of quantum gravity. String theory is a broad and varied subject that attempts to address a number of deep questions of fundamental physics. String theory has contributed a number of advances to mathematical physics, which have been applied to a variety of problems in black hole physics, early universe cosmology, nuclear physics, and conde ...

Bohemian Rhapsody
"Bohemian Rhapsody" is a song by the British rock band Queen, released as the lead single from their fourth album, '' A Night at the Opera'' (1975). Written by lead singer Freddie Mercury, the song is a six-minute suite, notable for its lack of a refraining chorus and consisting of several sections: an intro, a ballad segment, an operatic passage, a hard rock part and a reflective coda. It is one of the few progressive rock songs of the 1970s to achieve widespread commercial success and appeal to a mainstream audience. Mercury referred to "Bohemian Rhapsody" as a "mock opera" that resulted from the combination of three songs he had written. It was recorded by Queen and co-producer Roy Thomas Baker at five studios between August and September 1975. Due to recording logistics of the era, the band had to bounce the tracks across eight generations of 24-track tape, meaning that they required nearly 200 tracks for overdubs. The song parodies elements of opera with bombastic choruse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
