SOME RANDOM FACTS: 1. An iceberg contains significantly more total heat energy than a burning match. The reason is the sheer size of the iceberg. 2. Caves breathe. They inhale and exhale great quantities of air when the barometric pressure on the surface changes, and air rushes in or out seeking equilibrium. 3. While the chances of being struck by a meteor are extremely slim, there have been a number of documented cases: On June 21, 1994, Jose Martin of Spain was driving with his wife near Madrid when a 3-pound (1.4-kilogram) meteor crashed through his windshield, bent the steering whee-land ended up in the back seat. Martin suffered a broken finger while his wife was uninjured. 4. When a new queen bee emerges in a hive, she “pipes” (repeatedly sings a G# or A note) to incite her worker bees to fight for her if another queen in the hive needs killing. You can listen to the piping in the YouTube clip above. All bees pipe the same note – but Africanized bees pipe more frequently and louder. You can hear another clearer example here. The difference in pitch between the video clip and the sound file is cause by compression and quality of recording devices. 5. There is a current scientific hypothesis that the sun has a companion which is currently about1-1.5 light years away. It is believed that it has an elliptical orbit which, every 26 million years, sends matter towards the earth causing mass Extinction events. It was the discovery of these seemingly regular events that gave rise to the hypothesis in the first place. The star is predicted to be most likely a red or brown dwarf and has been named Nemesis or “Death Star”.
