Interesting Facts & Nuggets

🧬

A single strand of human DNA, if uncoiled, would stretch about 2 meters long. Your body contains ~37 trillion cells, giving you enough DNA to reach Pluto and back.

⚛

Hemoglobin (shown in our Chemistry Lab) contains 4 iron atoms. Each can bind one O2 molecule. That's why blood is red — iron + oxygen = red like rust.

🌏

Earth's tectonic plates move at roughly the speed your fingernails grow — about 2-5 cm per year. In 250 million years, all continents will merge again into a supercontinent.

☕

Caffeine (C8H10N4O2) blocks adenosine receptors in your brain, preventing the "sleepy" signal. It doesn't give energy — it prevents you from feeling tired.

🔭

Water's bond angle (104.5 degrees) makes it one of the strangest molecules. It expands when frozen, which is why ice floats — otherwise, lakes would freeze solid from the bottom up.

🚀

The Voyager 1 spacecraft is 24+ billion km from Earth. Its signal takes over 22 hours to reach us, traveling at the speed of light. It still runs on 1977 technology.
