Chemistry

  • Chemistry of Almost Everything

    Chemistry is involved in everything and is everywhere. This series explains how some of the processes work.

    Professor Steven Ley from Cambridge University discusses the development of a molecule in his research lab. He describes a compound so strong that just a tablespoon full would cover an area the size of two football pitches.

    We find out about the oil from Neem trees in India and the medical benefits it has. A hibernating frog and how he survives the freezing temperature. How humans survive in space and what role chemistry plays in this form of survival.

    A slum district in Delhi that recycles equipment so it can be re-used for teaching chemistry. The relationship between chemistry, peace and war. How using chemistry can make money, especially in the pharmaceutical business.

    How carbon plays a central role in the chemistry of creation. Sources of Nitrates and the developments in synthesizing nitrates. How chemistry continues after death - looking at the skeleton. Dangerous free radicals and their effect on the heart.

  • Crash Course: Chemistry

    Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff.

    Chemistry can tell us how three tiny particles - the proton, neutron and electron - come together in trillions of combinations to form... everything.

    We start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.

    A unit is the frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the international system of units.

    Hank thinks this is a thrilling subject, and while you may not agree, it is a subject that is very important if you want to be a scientist and communicate with accuracy and precision with other scientists.

  • Periodic Table of Videos

    The Periodic Table of Videos is a collaboration between the University of Nottingham's School of Chemistry and video journalist Brady Haran. They initially made videos about all 118 elements.

    Tables charting the chemical elements have been around since the 19th century - but this modern version has a short video about each one.

    They've done all 118 - but their job's not finished. Now they're updating all the videos with new stories, better samples and bigger experiments. For more info go to The Periodic Table of Videos.

  • SciShow: Chemistry

    Hank talks about a shiny element that has fascinated humans for millenia; and everyone's favorite squeaky-voice gas and why it's important for more than party balloons.

    Why our love affair with the rare earth elements has a dark side; and the awesomeness of the periodic table and the genius of the man who invented it.

    A sweet-tasting substance we humans just love - where it comes from, why we need it and how we could maybe stand to love it a little less.

    Hank delves into the details about that very popular substance: caffeine; the story of his favorite genius lady scientist and radioactive superhero, Marie Curie; and the high fructose corn syrup - the new "dark lord of nutrition" - to help explain the ambiguities around all the claims being made about it.

    Hank explains the science behind the effects of that wackiest of weeds, cannabis sativa - aka marijuana; and the man behind the periodic table - the brilliant Russian chemist Dmitri Mendeleev.

  • SciShow: Great Minds

    SciShow delves into the minds of some of humanity's greatest scientists. Some of them are:

    Dmitri Mendeleev - brilliant Russian chemist, the man behind the periodic table.

    Gregor Mendel - the Austrian monk who, with the help of a garden full of pea plants, discovered the fundamental properties of inheritance and paved the way for modern genetics.

    Alan Turing - openly gay man in the early 20th century faced brutal prejudice that eventually led to his suicide, despite being a genius war hero who helped the Allies defeat the Nazis.

    Fritz Haber - a great mind who is considered "the father chemical warfare," but who also made discoveries and innovations that helped lead to the Green Revolution which is credited with preventing the starvation of over a billion people.

    Elizabeth Blackburn - the Nobel Prize-winning Australian woman who discovered telomeres and telomerase, and helped scientists begin to understand the process of aging at a genetic level.

    Nikola Tesla - bizarre and eccentric genius with the crazy eyes who spent his life increasing awesome wherever he went, and contributed in some way to pretty much every cool invention you can think of.

    Nikola Tesla spoke eight languages and, at the time of his death, held over 700 patents and was being investigated by the US government for claiming to have invented a 60 million volt death ray. Tesla was an undisputed genius.
