Zitat des Tages über Periodisch / Periodic:
We need less memorization - I never memorized the periodic table of the elements - I've never used it, and I'm a physicist! I can look it up.
About seven years later I was given a book about the periodic table of the elements. For the first time I saw the elegance of scientific theory and its predictive power.
We had periodic crises in this country when the technical intelligence didn't support the policy. We had the bomber gap, the missile gap.
One day, when the world market is more or less fully developed and can no longer be suddenly enlarged, and if labour productivity continues to advance, then sooner or later the periodic clashes between productive forces and market barriers will begin, and because of their recurrence, these will naturally become increasingly rough and stormy.
The body tends to treat elements in the same column of the periodic table as equivalents.
Our country undergoes periodic episodes of extreme intolerance and fear of foreigners, refugees in particular. Not only were people of Japanese descent placed in internment camps during World War II, but so were some Italians and Germans.
After a few years of intensive research, we found a way to use a pulsed laser directed into a nozzle to vaporize any material, allowing for the first time the atoms of any element in the periodic table to be produced cold in a supersonic beam.
There are six components of wellness: proper weight and diet, proper exercise, breaking the smoking habit, control of alcohol, stress management and periodic exams.
Despite its obscurity, probably no element on the periodic table has as colorful a history as antimony. Money, madness, poison, linguistics, charlatanism, sex - pretty much every theme that runs through the periodic table can be found in Element 51.
If the human condition were the periodic table, maybe love would be hydrogen at No. 1. Death would be helium at No. 2. Power, I reckon, would be where oxygen is.
For most people, chemotherapy is no longer the chamber of horrors we often conceive it to be. Yes, it is an ordeal for some people, but it wasn't for me, nor for most of the patients I got to know during my four months of periodic visits to the chemo suite.
The squares of the periodic times are to each other as the cubes of the mean distances.
Boron is carbon's neighbor on the periodic table, which means it can do a passable carbon impression and wriggle its way into the matrix of a diamond. But it has one fewer electron, so it can't quite form the same four perfect bonds.
The noble gases, which reside on the East Coast of the periodic table, are its aristocrats - detached and aloof, never bothering to interact with the rabble of common elements that make up the vast majority of the world.
One theme I ran into over and over while writing about the periodic table was the future of energy and the question of which element or elements will replace carbon as king.
When very large stars die, they create temperatures so high that protons begin to fuse in all sorts of exotic combinations, to form all the elements of the periodic table. If, like me, you're wearing a gold ring, it was forged in a supernova explosion.
If studying the periodic table taught me nothing else, it's that the credulity of human beings for periodic table panaceas is pretty much boundless.
