What do you think is more probable — to get struck by lightning or to get killed by a falling asteroid? You might be surprised but the probability of death caused by an asteroid is almost twice as high. In their Book of General Ignorance, Stephen Fry, John Lloyd, and John Mitchinson say that lightning bolts strike the earth 17 million times each day, which is 200 strikes per second. Yet the risk of “electrical” death per year is one to 10 million, and that’s as probable as being bitten by a viper! cool stuff, cool stuff, cool stuff
We at Op-cast.com don’t believe that ignorance is bliss and we want our readers to be aware of the most recent facts and truths.
1. Chameleons don’t change their color depending on their surroundings.
It might have been useful in many cases, given that chameleons aren’t properly armed against anyone who’d like to eat them, but no. They never have and never will, though this belief is extremely popular. Truth be told, the color of a chameleon completely depends on its emotional state. And if it’s the same as the place where it currently is, then it’s totally coincidental. cool stuff, cool stuff, cool stuff
A chameleon changes its color when it’s scared, when someone picks it up, or when it has just beaten another chameleon in a fight. Temperature, light, and the presence of a female can also alter its looks. It’s interesting to know that a chameleon’s skin has several layers of special cells called chromatophores, each of which has its own color pigments. The change in the layers’ ratio makes the skin reflect different types of light, causing the chameleon to look like a moving disco ball.
By the way, the word “chameleon” means “an earthen lion” translated from Greek.
2. The blue whale isn’t the biggest living creature on Earth.
It’s huge, don’t doubt that, but it’s not the biggest one. The trick here is in an important nuance — the biggest living creature on Earth is, in fact, a mushroom. And its name is Armillaria Ostoyae, or, as it’s now known, Humongous Fungus.
The record-winning honey mushroom has been growing in Malheur National Forest, Oregon, USA, for approximately 2,000-8,000 years (the exact age of this giant creature cannot be estimated.) It occupies 880 hectares (2,200 acres), and its biggest part is hidden from the human eye. It spreads underground in the shape of a massive white mycelium. This mycelium covers the trees’ roots, survives off of them, and then eventually kills them. From time to time, it springs through the ground and starts growing on the surface disguising itself as a pretty little golden mushroom and not the giant it actually is.
3. Cockroaches won’t survive a nuclear war.
Many people tend to think that cockroaches are indestructible. Yes, they’ve been around for much longer than humans (approximately 280 million years) and are very hard to get rid of as house pests. Plus, they can live without a head for some time. But a scientific experiment held in 1959 showed that cockroaches will be among the first insects to die in case of a nuclear catastrophe.
2 scientists, Wharton and Wharton, put a large variety of insects under radiation of different levels. In the end, they came to the conclusion that a lethal dose for humans is 1000 rad, while for a cockroach, this number is 20,000 rad. A parasitic wasp will need 180,000 rad to end its life. Though the real winner here is a tiny bacteria Deinococcus durans because it can endure an amazingly high dosage of radiation — 1.5 million rad, and this number is doubled if the bacteria is frozen!
