The EmDrive May Violate The Laws Of Physics
1 of 24
Newton's third law of motion states that for every action, there is an equal and opposite reaction. Inside the EmDrive, a controversial propulsion system developed by British researcher Roger Shawyer in the early 2000s, that seems not to be the case. How is that possible?

For decades, physicists have been hard at work trying to answer the universe's unanswered questions. In October 2016, they may have solved five of them in one fell swoop.
Time Crystals Break The Continuity Of Time

In September 2016, a team of researchers from the University of Maryland announced that they had experimentally confirmed the existence of time crystals. That is, crystals that break the continuity of time. Confused? Let's break this down.
The Doppler Effect Tells You A Siren Is Passing And The Universe Is Expanding
4 of 24
You're probably familiar with the sound of a siren (or a car horn, or a rumbling semi truck) as it approaches and then passes you. The sound starts low and quiet, then begins to rise in pitch as it gets closer, then gradually drops in pitch as it passes and moves down the road. This change in pitch is known as the Doppler effect, and it may surprise you to learn that it's the same phenomenon that tells astronomers our universe is expanding.
Thank Physicist Michael Faraday For Your Electronics

Physicist and chemist Michael Faraday is credited for having said, "There's nothing quite as frightening as someone who knows they are right." But when it came to electromagnetism, Faraday got a lot of things just right. The scientist, born on September 22, 1791, in south London, made scientific discoveries and advancements that are present in almost all of the electronics we deal with today. Specifically, Faraday was a pioneer in the fields of electromagnetism and electrochemistry. In 1831, Faraday made the huge discovery of electromagnetic induction. This is the principle behind the electric transformer and generator, devices that are often used today. Discovering electromagnetic induction was a huge step in making electricity a tangible, practical, and powerful new technology, instead of just a curious concept. He was partly responsible for creating the words electrode, cathode, and ion. He also invented the Faraday cage, which is a shield that blocks electricity from affecting what's inside the cage. This technology is present in MRI machines, microwaves, and cables and is even responsible for the suits that power linemen wear.
