A prime number theory equation by mathematics professor emeritus Carl Pomerance turned up on The Big Bang Theory, where it was scrawled on a white board in the background of the hit sitcom about a group of friends and roommates who are scientists, many of them physicists at the California Institute of Technology.

In a recent paper, “Proof of the Sheldon Conjecture,” Pomerance, the John G. Kemeny Parents Professor of Mathematics Emeritus, does the math on a claim by fictional quantum physicist Sheldon Cooper that 73 is “the best number” because of several unique properties. Pomerance’s proof shows that 73 is indeed unique.

The Big Bang Theory is known for dressing the set with “Easter eggs” to delight the self-avowed science nerds in the audience. When UCLA physics professor David Saltzberg, technical consultant for The Big Bang Theory, heard about the Sheldon proof, he contacted Pomerance to ask if they could use it in the show, which was broadcast April 18.

The ultimate degree of control for engineering would be the ability to create and manipulate materials at the most basic level, fabricating devices atom by atom with precise control.

Now, scientists at MIT, the University of Vienna, and several other institutions have taken a step in that direction, developing a method that can reposition atoms with a highly focused electron beam and control their exact location and bonding orientation. The finding could ultimately lead to new ways of making quantum computing devices or sensors, and usher in a new age of “atomic engineering,” they say.

The advance is described today in the journal Science Advances, in a paper by MIT professor of nuclear science and engineering Ju Li, graduate student Cong Su, Professor Toma Susi of the University of Vienna, and 13 others at MIT, the University of Vienna, Oak Ridge National Laboratory, and in China, Ecuador, and Denmark.

THE results of a NASA test into “warp drive” technology have been leaked onto the internet — and apparently show it is possible.

The findings appear to be good news — that the new technology that could fly spaceships to Mars, put men on the moon in four hours and make flying cars possible actually works in theory.

The much-anticipated review of EmDrive space propulsion was not supposed to be released until December according to the International Business Times.

Physicists have long thought that the singularities associated with gravity (like the inside of a black hole) should vanish in a quantum theory of gravity. It now appears that this may indeed be the case. Researchers in Uruguay and Louisiana have just published a description of a quantum black hole using loop quantum gravity in which the predictions of physics-ending singularities vanish, and are replaced by bridges to another universe.

Tunneling, a key feature of quantum mechanics, is when a particle that encounters a seemingly insurmountable barrier passes through it, ending up on the other side. A series of experiments carried out by physicists from Griffith University, Lanzhou University, the Australian National University, Drake University and Korea’s Institute for Basic Science has definitively determined the tunneling delay, which is also the time it takes for an electron to get out or ionize from a hydrogen atom.

Breakthrough will help with the development of reliable quantum computers.

DENVER — Researchers have developed a new, unspeakably dangerous, and incredibly slow method of crossing the universe. It involves wormholes linking special black holes that probably don’t exist. And it might explain what’s really going on when physicists quantum-teleport information from one point to another — from the perspective of the teleported bit of information.

Daniel Jafferis, a Harvard University physicist, described the proposed method at a talk April 13 here at a meeting of the American Physical Society. This method, he told his assembled colleagues, involves two black holes that are entangled so that they are connected across space and time.

Researchers have learned how to produce electricity from Earth’s excess infrared radiation and waste heat through the unusual physics of quantum tunneling.
