10 ways to keep your Online Data Safe

In today’s digital world, banking, money transfers, and payments—as well as medical, corporate, and government records—are secured by means of complex encryptions. The ciphertext, in turn, is read by those who have the necessary decryption key to restore the data to its original form. Whereas a metal key usually has a set of grooves, a digital key is a string of zeros and ones in various combinations. Longer keys have more combinations and are thus harder to crack. An eight-bit key, for example, has 256 possible combinations, or permutations, whereas a 56-bit…

Earth’s magnetic Protection

The Earth’s magnetic field originates deep inside the planet and stretches far into space, where it forms an invisible shield called the magnetosphere. This shield protects us from the full force of cosmic radiation and from dangers emanating from the sun. The latter include the solar wind, which is a steady stream of energetic particles; solar flares, which release in minutes as much energy as billions of hydrogen bombs; and coronal mass ejections (CMEs), which blast billions of tons of matter from the sun’s corona into space. Both solar flares and CMEs trigger…

The Hidden Earth Vent Life Secrets

The ground beneath our feet is understood to be made up of a rigid layer (called the lithosphere) that rests on a mass of molten, slow-flowing rock. Apparently, this rigid outer layer averages some 60 miles [100 km] in depth and makes up only about 0.6 percent of the volume of the planet. The outermost part of it, the crust, is uneven, thicker beneath the continents and as thin as 3.5 miles [6 km] beneath the mid-ocean ridge system. Furthermore, this solid outer shell is not one piece, like the shell of an undamaged egg. Instead, it appears to…
