High-tech realization of Harry Potter magic

Recently, the finale of "Harry Potter 7" has hit the globe, setting off a wave of Harry Potter. No matter how Harry Potter's content and circumstances change, I believe that the real attraction to the audience is mystery. Magic device. At the moment, these mysterious magic may no longer be distant and they are gradually approaching people's lives and are becoming a reality.

Ultra-bent material woven into "Invisible Cloak"

Among the magic devices used by Harry Potter, the invisibility cloak is undoubtedly one of the coolest ones, allowing people to suddenly disappear without a trace.

Recently, British scientists have used a new type of material to create authentic versions of "invisibility garments." This material is called "hypercurved material." These artificial materials seem to ignore the laws of physics and their secondary microstructures refract in unusual ways. Light and sound. Scientists have been able to use ultra-bent materials to make objects, albeit nanometers. The newly developed ultra-bent material can refract light, making the object invisible at longer wavelengths. The "thin films" of superbly-curved materials are stacked together to create a flexible "smart fabric" that can achieve the basic function of an invisibility cloak.

Flexible electronic newspaper and "active newspaper photos"

In the magical world of "Harry Potter", black-and-white articles of the "Prophets Daily" are interspersed with photographs to show momentary object movements.

Although common devices, including smart phones, can display momentary images, they really cannot be rolled up like newspapers. A few years ago, the EU-funded FlexiDis project aimed to develop a new flexible display that not only folds like a newspaper, but also displays high-definition images. Sony is also developing a thinnest screen technology to date, laying the foundation for the manufacture of flexible full-color organic light-emitting diode screens. This summer, LG announced that the company will use metal foil instead of glass to make 19-inch flexible black and white electronic newspapers. Therefore, the advent of ultra-thin, flexible full-color e-book readers is only a matter of time.

IBM "Cestape Software"

In the movie "Harry Potter and the Order of the Phoenix," there is a mysterious "storage basin" that can store memories. This is a magic stone basin that can provide some memory storage.

In reality, this magic is not far away. For example, scientists at IBM Research Labs in the United States successfully developed a software in 2008 that can help people remember memories by recording images, sounds, and text messages based on their daily mobile phones. Get someone's name, face, call content, and other important content. Yakovi Navon, the project leader, compared the software to "a personal assistant in human memory."

“Wand” remote control has always appeared wands in each “Harry Potter” movie. This is one of the magic tools necessary for magicians.

In August of this year, the British inventor's newly developed “wandstick” remote controller became famous. This device is similar to the wand used by Harry Potter in science fiction movies, but in fact it is a universal remote control without buttons. Swish your wrist to control any infrared device. This wand remote control can not only change the channel, but also adjust the volume through 13 different gestures or pause DVD playback. The wand remote control is 35 cm long and is very convenient to use. Can be used for TVs, HIFI speakers, DVD players, laptops, and remote controls such as light switches and curtains.

Sonic Weapons More Powerful than “Disarmed Charm” In the “Harry Potter” series, a magician points his wand at another magician and reads in his mouth: “Release your weapon.” Immediately, a green spout comes out of his wand. Light, so that the other party's wand does not listen to call. Disarmed spells can even make opponents fall to the ground.

In the real world, scientists have developed sophisticated, non-lethal sonic weapons that are not as accurate as "disarming spells." A remote acoustic wave device (LRAD) releases high-energy sound waves. Sound waves point in a “bunch” to a target that is a mile away. Cheng Shengbo devices can release sound waves from 88 to 150 different decibels, which is larger than the sound produced by standard smoke detectors.

Remote acoustic wave devices have been used successfully, for example, to protect large cruise ships from Somali pirates armed with weapons such as rockets and machine guns. Sonic weapons are still controversial, and human rights organizations have criticized that high decibel noise still damages hearing.

Skycar M400 "Magic Speed ​​Car"

In "Harry Potter and the Chamber of Secrets," Harry Potter and Ron Wesley borrowed a magical car and quickly flew to the Hogwarts School of Magic. But in real life, cars that can fly in the air are no longer science fiction stories.

In 2005, the famous luxury product retailer Nimar Marcos Group declared that the Skycar M400, the world’s first flying car, was sold. The developer of this flying car is Miller International. The Skycar M400 can fly 34 gallons of alcohol with one gallon of alcohol and the top speed of the air can reach 560 kilometers per hour. The retail price of this vehicle is allegedly about 3.5 million US dollars.
