Faster than light? Relative speed of two photons approaching each other
Do two photons approach each other at twice the speed of light, 2 c ? This popular question highlights the distinction between relative and closing speeds in Newtonian physics and their interpretation within the context of special relativity. In everyday Newtonian usage, when we mention that two cars are approaching each other at, say, 100 km/h, we typically refer to the closing speed, determined as the sum of the speeds of both cars. However, the relative speed is also calc

Why is the ISS a weight-free zone in the sea of gravity?
The International Space Station (ISS) ( Fig. 1 ) is a laboratory the size of a mansion, orbiting Earth at an altitude of 250 miles (400 km). It was assembled in space using modules sent into orbit in separate launches, because no rocket is powerful enough to launch such a large structure in one piece. The station features habitable areas with breathable air for astronauts, as well as airless sections housing machinery operated by robotic arms, which are accessible only via sp

We Are Made of Stars. Tracing Human Origins Back to the Big Bang
The phrase "We are made of stars" was commonly used as a poetic metaphor to highlight the beauty of the human spirit. It was never anticipated to hold any scientific value, let alone accurately describe our physical makeup.

Potato Paradox: a clever play on common confusion about percentages
Problem . Fred brings home 100 kg of potatoes, made up of 99% water. He leaves them outside, allowing for some water to evaporate, thus reducing the water content to 98%. How much do the potatoes weigh now? Answer . The new weight is 50 kg. Fig 1 . Potatoes contain about 80% water on average. Solution . At first glance, the answer might seem illogical. The water content dropped by only 1%, so the weight shouldn't change much. However, the solid content doubled from 1% to 2
