Chemistry is the scientific discipline involved with compounds composed of atoms, i.e. elements, and molecules, i.e. combinations of atoms: their composition, structure, properties, behavior and the changes they undergo during a reaction with other compounds. Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are four types of chemical bonds: covalent bonds, in which compounds share one or more electron(s); ionic bonds, in which a compound donates one or more electrons to another compound to produce ions (cations and anions); hydrogen bonds; and Van der Waals force bonds.
We can no more have exact religious thinking without theology, than exact mensuration and astronomy without mathematics, or exact iron-making without chemistry,
John Hall (Presbyterian pastor) (1895) Dictionary of Burning Words of Brilliant Writers p. 580.
Modern warfare, we discovered, was to a far greater extent than ever before a conflict of chemists and manufacturers. Manpower, it is true, was indispensable, and generalship will always, whatever the conditions, have a vital part to play. But troops, however brave and well led, were powerless under modern conditions unless equipped with adequate and up-to-date artillery (with masses of explosive shell), machine-guns, aircraft and other supplies. Against enemy machine-gun posts and wire entanglements the most gallant and best-led men could only throw away their precious lives in successive waves of heroic martyrdom. Their costly sacrifice could avail nothing for the winning of victory.
David Lloyd George (1938) War Memoirs
Chemists usually write about their chemical careers in terms of the different areas and the discrete projects in those areas on which they have worked. Essentially all my chemical investigations, however, are in only one area, and I tend to view my research not with respect to projects, but with respect to where I’ve been driven by two passions which I acquired in graduate school: I am passionate about the Periodic Table (and selenium, titanium and osmium are absolutely thrilling), and I am passionate about catalysis. What the ocean was to the child, the Periodic Table is to the chemist; new catalytic reactivity is, of course, my personal coelacanth.

In June 1770, the explorer James Cook ran aground on the Great Barrier Reef in Australia and became the first European to experience the world's largest coral reef, today a paradise for scientists and holidaymakers alike. Last year, the James Cook research vessel set out to encounter unique and unexplored corals, this time in the deep ocean. Led by ERC grantee Dr Laura Robinson (University of Bristol, UK), the team on board crossed the equatorial Atlantic to take samples of deep-sea corals, reaching depths of thousands of meters. On the expedition, Dr Robinson collected samples that are shedding light on past climate changes and she will share her findings at TEDx Brussels.
