Steven Weinberg, one of the greatest theoretical physicists of all time, passed away on 23 July, aged 88. He revolutionised particle physics, quantum field theory and cosmol_ogy with conceptual breakthroughs that still form the foundation of our understanding of physical reality.CERN courier...
While this experiment is not splitting any atoms, as such, it was a key part of the decades-long effort to understand what atoms are made of—and in that sense, it did help physicists to "split" (venture inside) the atom. 9: Enrico Fermi demonstrates the nuclear chain reaction (1942) ...
Theoretical physicists stare at blackboards, do calculations and make predictions. Experimental physicists build equipment, gather observations and analyse data sets. (At least, that’s how it goes at the best of times.) The two groups are reliant on each other – experimentalists may be trying ...
For these achievements he is widely considered to be one of the three or four greatest theoretical physicists ever. Archimedes was a prolific inventor: in addition to inventing the compound pulley, he invented the hydraulic screw-pump (called Archimedes' screw); a miniature planetarium; and ...
Physicistscontinue to carve the known universe into particles to describe everything frommagnetism to what atoms are made of and how they remain stable. Yet strikingsimilarities in the world of quantum mechanics, as the study of particles andtheir forces is known, has led to a one of the ...
His work inspired all three of the greatest 20th-century mathematical physicists, laying key mathematical groundwork for Weyl's unified field theory, Einstein's relativity, and Dirac's quantum field theory. Henri Léon Lebesgue (1875-1941) France -- [ #93 ]...
Theoretical physicists: Eleven. One does the job, ten join as co-authors. Nuclear engineers: One to install the bulb and six to figure out what to do with the old bulb for the next ten thousand years @Dean @Sean T @Wow None “Bright light - hurts... must go back to bed” ...
Before exploring for new elements with Pierre, Marie Curie followed in the footsteps of one of her favorite physicists, Henri Becquerel. His work with uranium led to the discovery of forms of radiation weaker than X-rays. From here, Curie went on to describe these actions as "radioactivity" ...
Then, sixty-nine years later, in 1998, science exhumed lambda one last time, because now there was evidence to justify it. Early that year two teams of astrophysicists--one led by Saul Perlmutter of Lawrence Berkeley National Laboratory in Berkeley, California; the other by Brian Schmidt of ...
apart when it crosses the “event horizon”, which is a theoretical limit around a black hole beyond which escape is impossible once an object crosses it. The destruction of the object releases huge amounts of X-rays and other radiation, which reveals the location, or presence of a black ...
