![]() In scientific research, the behavior of the two fluid phases of helium-4 (helium I and helium II) is important to researchers studying quantum mechanics (in particular the property of superfluidity) and to those looking at the phenomena, such as superconductivity, produced in matter near absolute zero. ![]() As with any gas whose density differs from that of air, inhaling a small volume of helium temporarily changes the timbre and quality of the human voice. A small but well-known use is as a lifting gas in balloons and airships. Helium's other industrial uses-as a pressurizing and purge gas, as a protective atmosphere for arc welding, and in processes such as growing crystal to make silicon wafers-account for half of the gas produced. Liquid helium is used in cryogenics (its largest single use, consuming about a quarter of production), and in the cooling of superconducting magnets, with its main commercial application in MRI scanners. In 1903, large reserves of helium were found in natural gas fields in parts of the United States, by far the largest supplier of the gas today. ![]() The formal discovery of the element was made in 1895 by chemists Sir William Ramsay, Per Teodor Cleve, and Nils Abraham Langlet, who found helium emanating from the uranium ore, cleveite, which is now not regarded as a separate mineral species, but as a variety of uraninite. Lockyer was the first to propose that the line was due to a new element, which he named after the sun. Janssen recorded the helium spectral line during the solar eclipse of 1868, while Lockyer observed it from Britain. Janssen is often jointly credited with detecting the element, along with Norman Lockyer. Pogson, and Lieutenant John Herschel, and was subsequently confirmed by French astronomer Jules Janssen. Helium was first detected as an unknown, yellow spectral line signature in sunlight during a solar eclipse in 1868 by Georges Rayet, Captain C. Large amounts of new helium are created by nuclear fusion of hydrogen in stars. The most common isotope of helium in the universe is helium-4, the vast majority of which was formed during the Big Bang. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. Its abundance is similar to this in both the Sun and in Jupiter, due to the very high nuclear binding energy (per nucleon) of helium-4, with respect to the next three elements after helium. It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. It is the second lightest and second most abundant element in the observable universe, after hydrogen. Its boiling point is the lowest among all the elements, and it does not have a melting point at standard pressure. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Helium (from Greek: ἥλιος, romanized: helios, lit.'sun') is a chemical element with the symbol He and atomic number 2. As one of the hottest comedians in the business, Rife has been selling out at comedy clubs and theaters all across the country and is gearing up to embark on his biggest tour yet in 2023.0.95 K (−272.20 ☌, −457.96 ☏) (at 2.5 MPa) In 2021, Rife self-produced and distributed through YouTube his first one-hour comedy special, "Only Fans". He made his television debut on MTV's "Wild 'N Out" as the youngest cast member in history for four seasons before moving on to other MTV properties, such as hosting the reboot of "TRL" and appearing on "The Challenge." Other credits include: "Brooklyn Nine-Nine", "Fresh Off The Boat", BET's "North Of The 10", and most recently NBC's comedy competition show "Bring The Funny." From Columbus Ohio, Matt started performing at the age of fifteen opening for comedians such as Dane Cook, Ralphie May, and DeRay Davis. Rife brings forth his refreshingly genuine presence along with elevated material that is quick witted and vulnerable. Matt Rife has exploded as one of the fastest growing comedians through his viral content and remarkable engagement on TikTok, where he has amassed over 5 million followers, and more than 260 million views globally.
