Used to identify organic compounds.

Seems to be based on the effects that electrons around the nuclei (shielding electrons) have on the outcome of NMR.

So it is a bit unlike MRI where you are interested in the position of certain nuclei in space (of course, these being atoms, you can't see their positions in space).

Ciro Santilli is mildly obsessed by nuclear reactions, because they are so quirky. How can a little ball destroy a city? How can putting too much of it together produce criticality and kill people like in the Slotin accident or the Tokaimura criticality accident. It is mind blowing really.

The Whittaker model, often referred to in various contexts, primarily pertains to mathematical and statistical modeling in different fields, such as ecology, finance, and natural sciences. However, one of the more prominent references is the Whittaker model in the context of population dynamics and ecology. ### Whittaker's Classification of Plant Communities: In ecology, the Whittaker model refers to a classification system developed by the ecologist Robert Whittaker in the 1950s.

Gun-type fission weapons are the simplest approach and they work with Uranium-235 bombs as you can ignite it with just one explosion.

But Gun-type fission weapons don't work with plutonium, and weapon grade Plutonium is cheaper than weapon grade Uranium, so it wasn't much used.

Implosion-type fission weapons are more complicated than gun-type fission weapon because you have to precisely coordinate the detonation of a bunch of explosives.

The B Reactor of the facility produced the plutonium used for Trinity and Fat Man, and then for many more thousand bombs during the Cold War. More precisely, this was done at

Located in Washington, in a dry place the middle of the mountainous areas of the Western United States, where basically no one lives. The Columbia river is however nearby, that river is quite large, and provided the water needed by their activities, notably for cooling the nuclear reactors. It is worth it having look on Google Maps to get a feel for the region.

Unlike many other such laboratories, this one did not become a United States Department of Energy national laboratories. It was likely just too polluted.

The lab that made Chicago Pile-1, located in the University of Chicago. Metallurgical in this context basically as in "working with the metals uranium and plutonium".

Given their experience, they also designed the important X-10 Graphite Reactor and the B Reactor which were built in other locations.

The term "Jewish American physicists" refers to physicists in the United States who are of Jewish heritage or descent. This group includes many notable scientists who have made significant contributions to various fields of physics, including theoretical physics, experimental physics, and applied physics.

The term "generatrix" can have different meanings depending on the context in which it is used: 1. **Mathematics and Geometry**: In geometry, a generatrix is a curve or line that generates a geometric surface or solid through motion. For example, when a straight line (the generatrix) moves along a path (the directrix), it can create shapes such as cylinders, cones, or other solids. The generatrix is crucial in the definition of various three-dimensional shapes.
