Science is full of fascinating facts and discoveries, some of which we may have used to know and have now forgotten. Here are a few examples of little-known science facts that are sure to surprise and intrigue you:
-
The human nose can detect more than 1 trillion different scents, making it one of the most sensitive and complex organs in the body.
-
The Earth’s atmosphere extends much further than most people realize. In fact, it extends more than 600 miles (965 km) into space, and is held in place by the planet’s gravity.
-
Water is much more dense in its solid form (ice) than in its liquid form. This is why ice floats on top of water, rather than sinking to the bottom.
-
The human brain is capable of generating more electrical impulses in a single day than all of the telephones in the world combined.
-
The surface of the Sun is constantly moving, with different areas rotating at different speeds. This causes the Sun’s surface to appear to have a mottled, or “granulated,” texture.
-
The human ear is capable of detecting a wide range of sounds, from the softest whisper to the loudest explosion. In fact, the ear is so sensitive that if all of the sounds in the world were played at once, the human ear would still be able to pick out a single person’s voice.
These are just a few of the many fascinating and little-known facts about science. There is always more to learn and discover, and the world of science is full of surprises.
