These bats even make specific sounds to express unwanted mating advances, showcasing their complex social interactions.

8. Revenge in the Spam World

Talk about some poetic justice!

9. Stephen Hawking’s Unbelievable Lifespan

When Stephen Hawking was diagnosed with ALS, doctors gave him just two years to live. Yet, he defied the odds and lived for 55 more years. His incredible perseverance and groundbreaking work in the field of theoretical physics made him one of the most renowned scientists in the world.

10. The "Rising Sun" Flag Controversy

Many people are familiar with Japan’s national flag, which features a red sun. However, a lesser-known version of the flag, called the "rising sun" flag, has been a source of controversy.

11. Roulette and the Computer Edge

In the 1990s, a man used a computer to track the results of a roulette wheel at a Spanish casino. By analyzing the data, he was able to predict the next likely outcomes and won a staggering €600K.

15. The First Chatbot

In the 1960s, MIT professor Joseph Weizenbaum created a program called ELIZA, which simulated a psychotherapist. It was so convincing that some users, including Weizenbaum’s secretary, became emotionally attached to it. In fact, ELIZA was so advanced that it even outperformed modern AI models like GPT-3.5 in a recent Turing test. It’s a fascinating look at how far we’ve come in the world of artificial intelligence.
