Particle accelerators: What are they, how do they work and why are they important to us?
A particle accelerator is a machine that accelerates particles. More specifically, it accelerates elementary particles, like protons and electrons, at extremely high speeds—almost 99.99% of the speed of light. These particles are then...

Mirage: Why Does It Look Like There's Water On The Road?
The fake puddles of water that we see on the road on a sunny day is due to an optical phenomenon called a mirage, which is caused by the refraction (or bending) of light rays due to different temperatures of the air above the road. On a...

How Do Neurons Work?
Neurons send signals through a mechanism called action potential. Action potentials are electrical signals that pass through the neuron’s axon. This causes the neuron to pass the signal to the next neuron. Action potentials are the...

Giganotosaurus vs. T Rex: Who Was The Deadliest Predator?
Tyrannosaurus Rex is, without a doubt, one of the coolest out of all the dinosaurs. With its enormous size, speed, and killer power, it’s hard to deny that it was ferocious, fierce, and beautiful. Well, at least as long as beauty is...

Can Light Escape a Black Hole?
Light is affected by black holes because of the theory of general relativity, which states that any massive object warps the spacetime around it. Since a photon travels by the shortest distance between two points, light appears to bend...

Can You Survive a Gunshot to The Head?
There is a very low chance of surviving a gunshot to the head, but even if you do survive, you cannot come out of such an injury unharmed, which is why gun violence is one popular media depiction that no one wants to see translated into...

Breaking The Sound Barrier: Can Pilots Hear Sonic Booms?
When a plane, or in fact anything, travels faster than the speed of sound (i.e., breaks the sound barrier), a loud boom is heard, commonly known as a sonic boom. You may have heard that particularly loud, sometimes even painful boom when...

Why Don't Commercial Planes Fly Faster?
The main reason commercial aircraft have not gotten any faster in recent decades is due to fuel efficiency. Airplanes consume more energy the faster they fly, so airplane manufacturers favor slower speeds to save on operating costs....

Why Don't Buses Have Seatbelts?
The most important feature of the bus that nullifies the need to have seat belts installed is compartmentalization. Seats are installed equidistant with respect to each other, segregating passengers in small compartments of sorts. To put...

Why Do Wheels Appear to Spin Backwards (at High Speeds)?
At high speeds, wheels may appear to be turning backwards, creating an optical illusion known as the Wagon wheel effect. This happens because our brains fill in gaps between images to create the illusion of continuous movement. As a...

Why Do We Feel So Thrilled By Speed?
As you ‘floor’ the pedal, there is a sudden spurt of adrenaline in your body, which in turn has many effects: your blood pressure rises instantly, your heartbeat races, your body temperature rises, and you can feel a slight tingling...

Why Do Airplane Wings Bend Upward?
The curved shape of an aircraft wing, known as a winglet, helps to reduce the amount of drag created by the wingtip vortices. Since the 1980s, winglets have been a major part of future aircraft designs. For some old aircraft, winglets...

What Would Happen If You Traveled At The Speed of Light?
If you travel at the speed of light, your mass will increase exponentially. The speed of light is 300,000 kilometers per second (186,000 miles per second). When you move at this speed, your mass will become infinite. Therefore, infinite...

What Would Happen If Earth Rotated Faster?
An increase in Earths rotational speed could have various impacts on life: ranging from increased earthquakes and tsunamis to a shortening of the length of the day. People could be floating in central Africa while the polar ice might...

What is the Heisenberg Uncertainty Principle: Explained in Simple Words
Heisenbergs uncertainty principle says that if we know everything about where a particle is located, we know nothing about its momentum. Conversely, if we know everything about its momentum, then we know nothing about where the particle...
