How Your Memory Works
Sherlock Holmes, the renowned detective, believed that the brain is like an attic with limited storage for memories. He prioritized filling the attic with important details, such as identifying differences between lethal poisons, rather than cluttering it with random facts and trivia. But was Holmes correct? Is our memory capacity limited, akin to a computer's storage, or is it unlimited? And what would life be like if we had perfect memory and never forgot anything?
Is Earth Actually Flat?
In 2003, researchers conducted measurements and discovered that Kansas is actually flatter than a pancake. However, it's important to note that the Earth is not flat but round. If the Earth were a flat disk instead of a spherical shape, gravity would behave differently as you move towards the edge. My friend Nick from 'yeti dynamics' created a simulation demonstrating this effect. As a runner approaches the edge, gravity would make it feel like they are climbing a steeper hill. Buildings near the edge would need to be constructed in a way that maintains a sense of "down" being perpendicular to the floor, just like on our round Earth. Approaching the edge would be scary, as it would feel like a sheer drop-off. However, this model ignores the fact that a flat disc-shaped planet would eventually collapse due to gravity, making it impossible.
The surprising effects of pregnancy
Just days after fertilization, the embryo implants in the lining of the uterus. Because its DNA doesn’t exactly match the mother’s, the immune system should theoretically recognize it as an invader, attack, and destroy it, like it would bacteria or other harmful microbes.
What Happened to the Other Two 'Titanics'?
The story of the Titanic is well-known, but few are aware of its two sister ships. On the fateful night of the Titanic's sinking, one of its sister ships was rushing to its aid but arrived too late. Despite their shared ill luck, each of these ships had memorable moments etched in the memories of those who sailed on them.
Is it normal to talk to yourself?
As the blaring sound of your morning alarm fills the room, you grumble to yourself, "Why did I set it so early?" While briskly brushing your teeth, a thought crosses your mind, "I really need a haircut... unless?" Hurriedly rushing out of the front door, you reach out for your keys, only to realize they're nowhere to be found. Frustration takes hold, and you exclaim, "I can't seem to get anything right!" But just in the nick of time, you spot your neighbour nearby. Being caught in a moment of self-talk can be embarrassing, as some people unfairly label it as a sign of mental instability.
