Dead or depleted batteries, especially cylindrical ones like AA or AAA batteries, can exhibit a unique behavior known as "bouncing" when dropped from a short height. This phenomenon is primarily due to changes in the battery's internal chemistry and physical properties as it becomes discharged.

Inside a battery, there are chemical reactions that generate electrical energy. As a battery discharges and its chemical energy is depleted, its internal chemistry changes. One of the changes that occur is a reduction in the pressure of gases within the battery. This decrease in gas pressure can make the battery feel lighter, contributing to its bounce.

As a battery discharges, its internal components, such as the cathode, anode, and electrolyte, unde ...

According to a recent study conducted by researchers at the University of Grenoble in France, the results published were plain and simple - men who enjoyed dipping their food into hot, spicy sauce happened to have higher levels of free testosterone floating around their bloodstream after the meal. Salt preference, however, didn’t seem to have any link to testosterone levels. What does this correlation entail? Does capsaicin - the chemical responsible for spiciness - increase testosterone, or are those who are more likely to take risks possess higher levels of this potent male hormone? ...

India’s tiger population has risen from 1,706 individuals to 2,226 in the past four years, officials have reported. With the global population teetering around 3,000 individuals, this kind of growth is incredible.

This pictures speaks for itself.

Here's absolute zero (-273.15°C) to absolute hot (1,420,000,000,000,000,000,000,000,000,000,000°C) and everything in between.

A parasitic worm called Onchocerca volvulus affects 25 million people around the world in one of the most revolting ways possible. The larvae of this tiny worm, found in sub-Saharan Africa and Latin America, can live for more than 10 years in a person’s skin, and that’s not even the worst part - they often make their way into their eyes.

In this video, sand is sprinkled onto a metal plate attached to a speaker, which is then turned up the to bring the whole thing to life in a pulsating, dance of intricate patterns.

I am not sure if such blogs are welcome here, but I will try sparking enthusiasm in this subject. Alongside my major field of interest, I have an unhealthy/obsessive curiosity distortion in the archaeology field, specifically Egyptology. And recently, two major discoveries have been made in the Ancient Egyptian land.

The first discovery made was that belonging to an Ancient Queen named Khentakawess's the 3rd's tomb, which was located near her husband's tomb, Pharoah Neferefre. These two, date back to the 4th or 5th dynasties, that is approximately 4000 years back in history. Around that time, the first three pyramids, yes, the ones that we see all the time and are the most famous pyramids of Giza, were being built by Pharoahs Khufu, his son ...
