3 scientific events in the 2nd week of April

The new method reconstructs the three-dimensional image of the red rose using light white light instead of laser.

1. Create 3-D effects without glasses

A new type of 3D hologram provides 3-D images without glasses. And unlike many traditional holograms, this 3-D image is colored. Currently 3-D television technology is based on image overlapping techniques to create the illusion of depth. But new techniques, developed by Japanese scientists, were published in the journal Science, April 8, 2011, using white light to create electronic energy in a thin film. metal. This energy shows a three-dimensional image that appears for a period of 1 second, before it is engraved with a laser. Colorful colors of apples, roses and Japanese Paper Cranes created in this way, will maintain their appearance when viewed from a variety of angles, unlike floating forms. Three-dimensional is used on credit cards, according to Devin Powell.

2. Generate X-ray rays by rubbing

This is a simple way to create X-rays, and this could lead to the creation of portable, specialized X-ray devices for health professionals. Dr. Seth Putterman, a physicist, who works at UCLA, has built a hard, resilient epoxy resin shock absorber up to 20 times a second. Each impact will release X-ray energy, repeatedly touching the door handle can also release a lower energy than static impact as mentioned above. The mechanism of discharging electrical energy due to the effect of this friction, even removing a piece of adhesive tape from the contact surface, also generates X-ray rays, in most cases still not possible. understand. By testing different materials, Putterman hopes to increase the power of X-rays by 10 times, to create an X-ray generator that can run with a 12-volt battery, according to Devin Powell.

3. The new record binds quantum bits together

A new world record for binding quantum bits together, or qubits , gives quantum computing a step closer to usefulness. A group of researchers synthesized 14 atoms to form some of the same properties as a single quantum particle. This remarkable success is more than the previous 10-bit quantum record. The results of this study were published in Physical Review Letters, published on March 31, 2011, which also found a problem that quantum computers would face as the number of bits. Quantum will continue to increase: As the number of qubits increases, it will boost computing power, the stability of special quantum states allows atoms to store information faster than expected. .
