The measure of achievement is not winning awards. It's doing something that you appreciate, something you believe is worthwhile. I think of my strawberry souffle. I did that at least twenty-eight times before I finally conquered it.
The history of man is the history of crimes, and history can repeat. So information is a defence. Through this we can build, we must build, a defence against repetition.
Some plants are carnivores, gaining nutrients by eating various small insects and spiders. A well known example of a carnivorous plant is the Venus Flytrap.
Alkali metals such as sodium, potassium, rubidium, caesium and francium are extremely reactive elements, just putting them in water can result in an explosion! They are carefully stored in oil to prevent this happening.
While aluminum is the most common metal found in the Earth's crust, the most common metal found on Earth is iron, mostly because it makes up such a large part of the Earth's core.
