Which is still pretty lousy, it means for every megawatt of electricity you pump in to the antimatter-maker you would only obtain enough antimatter to create a mere 100 pathetic watts. The theoretical maximum is 50% due to the pesky Law of Baryon Number Conservation (which demands that when...

The actual full bown Doomsday Argument does not put any upper limit on the number of humans that will ever exist, nor provide a date for when humanity will become extinct. There is however an abbreviated form of the argument does make these claims, by confusing probability with certainty. You...
The number of transistors increased from 2,300 in 1971 to 1.5 billion in 2015. Today, computer processors, such as the recently announced Apple A12 Bionic chip and Huawei Kirin 980, use 7 nm processes with 6.9 billion transistors on a centimeter square chip. The limits are being pushed to ...
TMD materials have recently attracted a boom of scientific and technological activities due to the discovery of the direct bandgap of monolayer MoS2 and its related exciton physics1,2. In addition to the excitonic aspect, these materials possess a number of attractive characteristics, including excelle...
Chemical properties would thus have to depend on the number and constellations of these corpuscles inside the atom. They would have to have stable positions in it, bound by electrostatic and possibly kinetic forces. Because under normal conditions chemical atoms are electrically neutral, the total ...
the presence of many thousands of electrons, given the mass of an atom), the number of electrons considered in the model he put forth in 1904 was never more than on the order of 100; the majority of the first half of his paper is devoted to the problem of rings containing less ...
Core crew is about 80, and represents the minimum number of crew for a long-duration warship. Additional crew is fairly linear, at 1 crew per 100 tons of vessel. Automation will eventually halve these figures. Ken Burnside says that for routine operations of a warship, you need a minimum ...
The termination criterion of the algorithm is the maximum number of iterations (Tmax), where Tmax is equal to 100 and also (T ≤ Tmax). STEP 6-Update In this step, the best solution found by the algorithm is updated as the current solution. The algorithm then returns to step 2 to ...
Here, E R = ℏ 2 q B 2 / 2 m is the recoil energy, m is the mass of atoms, q B = π / d is the Bragg wave number (note that q B is different from the fundamental vector of a 1D reciprocal lattice, 2 π / d , by a factor of 2), and d is the lattice constant,...
