From ridicule to Nobel: The quasi-crystals of Daniel Shechtman

In 1982, Daniel Shechtman was on sabbatical at Johns Hopkins University studying aluminum-manganese alloys, and discovered that the resulting crystalline patterns of the alloy resulted in five-way symmetry, much like the famed Penrose Tiles. The resulting publication of these "quasicrystals" resulted in scathing ridicule from most of the scientific community, including Linus Pauling saying "There is no such thing as quasicrystals, only quasi-scientists.", and his research director claiming he had "Brought disgrace" upon their program. However, by 1987 he had managed to grow large enough crystals to be imaged with electron microscopy, verifying his results. His subsequent studies of quasicrystals eventually earned him the 2011 Nobel Prize in Chemistry.

Thermite and other memorable experiments

Unsafe-science-experiments-you-did-in-class-Friday: an advisory on dangerous chemistry experiments (they mention Nitrogen Triiodide, Chromate Volcanos, Whoosh Bottles, and Potassium Chlorate and Sugar), unwise microwave oven experiments, and, of course, thermite (and a great thermite video). I am amazed anyone survives high school, what other dubious but educational experiments did you do? Note: all pages are science education sites. Read the warnings. The awesome Chemistry Comes Alive site mentioned prev.

New Elements: Uut and Uup

Time to replace your old Periodic Table. ...a joint American-Russian team has found two new elements—numbers 113 and 115 on the periodic table—hinting at an impending breakthrough in creating novel forms of matter that will test our understanding of atomic behavior.

Exam Fun

Sorry, you've flunked. This gave me the best laugh I've had all week. I love the way you can tell the teacher marking the paper is getting more and more pissed off by the increasing ferocity of the red pen strokes. Heheheh. Give the kid an A.

Interesting Chemistry

I don't remember chemistry being this interesting.
