The standard strategy for doing this, since the work of Bourgain and then Wolff in the 1990s (with precursors in older work of Córdoba), is to perform some sort of “induction on scales”. Here is the basic idea. Let us call the tubes in “thin tubes”. We can try to group these...
Planck had sought to discover the reason that radiation from a glowing body changes in color from red to orange and, finally, to blue as its temperature rises. He found that by assuming energy existed in individual units in the same way thatmatterdoes, rather than just as a constant electro...
Also, for a person to teleport, the teleporter's computer would have to pinpoint and analyze all of the 1028 atoms that make up the human body. That's more than a trillion trillion atoms. This wonder machine would then have to send the information to another location, where another amazin...
Where this analogy breaks down, however, is that we cannot step outside the universe because there is no outside to step into. By definition, the universe is everything in existence, so nothing can exist outside it. That said, modern theories such as chaotic inflation, brane theory and ...
Werner Heisenberg discovered the uncertainty principle, which states that the position and the momentum of an object cannot both be known exactly. The combined uncertainty for position and momentum is equal to or greater than h/(4π), where h is Planck’s constant, and thus is significant ...
Over time, however, these free electrons met up with nuclei and created neutral atoms or atoms with equal positive and negative electric charges. This allowed light to finally shine through, about 380,000 years after the Big Bang. Sometimes called the "afterglow" of the Big Bang, this light...
a0is the Bohr radius. ℏ is the reducedPlanck constant. α is the fine-structure constant. meis the mass of an electron. c is the speed of light in a vacuum. The Bohr radius is derived from the Bohr model of the atom. The Bohr radius is derived from the Bohr model of the atom...
ΔΕ is the uncertainty in the measured value of the energy; Δt is the uncertainty in the time at which the measurement is made; h is Planck’s constant. (2) Here’s an example: fundamental particles—pions and muons—are generated when cosmic rays penetrate the earth’s atmosphere (see...
