Quotes About Isotopes

The discovery of slow-neutron radioactivity meant that Fermi's group had to work its way through the elements again looking for different and enhanced half-lives—which is to say, different isotopes and decay products.

Ice cores, which are long cylinders scientists extract from glaciers, ice sheets or ice caps, contain gas bubbles, pollen, dust particles, or chemical isotopes that give scientists clues about what Earth's temperature and atmosphere were like when the ice caps first formed.

The discovery of deuterium and the marked differences in the physical and chemical properties of hydrogen and deuterium, together with an efficient method for the separation of these isotopes, have opened an interesting field of research in several of the major branches of science.

these were physically variant forms of the familiar elements. These different forms of an element are chemically identical—hence the same element—but physically different. These distinct varieties are called isotopes, from the Greek for 'equally placed' (in the periodic table of the elements).

I wonder what the most intelligent thing ever said was that started with the word 'dude.' 'Dude, these are isotopes.' 'Dude, we removed your kidney. You're gonna be fine.' 'Dude, I am so stoked to win this Nobel Prize. I just wanna thank Kevin, and Turtle, and all my homies.'

We hope that this honor you have done us will bring the time of further realization of these benefits closer and will help all mankind to live better and be happier through the atom and isotopes.

Among the tiny atomic structures the plankton take to the grave with them are two very stable isotopes—oxygen-16 and oxygen-18.

I've been focused on detecting nuclear terrorism at ports, in cargo containers, and I developed and built detectors that are extremely cheap and also very sensitive. My other big development is a system to produce medical isotopes that are injected into patients and used to diagnose and treat cancer.

The biggest battle I fought with the danger officer was over the fact that I insisted on keeping my lunch and a case of Beck's beer in the same fridge in which I kept my radioactive isotopes.

This weird behavior is a manifestation of quantum sync. All liquids become highly ordered when cooled to very low temperatures. Normally they freeze into a crystal. But the two isotopes of helium, helium-3 and helium-4, never solidify, at least not at ordinary pressures. They remain liquids all the way down to absolute zero.

I don't believe their minds were so different from ours that we're in danger of wildly misinterpreting anything that looks like a simple message. So far, the worst mistake we could have made would have been to give up too soon on trying to interpret the isotopes.

In general, exchange reactions for the lighter isotopes have equilibrium constants sufficiently different from unity, so that the ratios of concentrations of the isotopes in two compounds which are in equilibrium differ by a few per cents in nearly all cases.

As I regard physics and psychology as complementary types of examination, I am certain that there is an equally valid way that must lead the psychologist 'from behind' (namely, through investigating the archetypes) into the world of physics. As an example of background physics, I shall discuss a motif that occurs regularly in my dreams - namely, fine structure, in particular doublet structure of spectral lines and the separation of a chemical element into two isotopes.
