In a landmark discovery about the first moments of the universe, a team led by a Harvard astronomer announced it had found strong evidence of what happened just after the Big Bang 13.8 billion years ago:

In the slightest fraction of a second, the universe — a speck one-billionth the size of a proton — doubled in size 100 times over, a dramatic expansion called inflation. Scientists call it the “bang” of the Big Bang.

Those who are interested in science forever live a world of wonder. Keep exploring, friends! :)

A rich merchant had collected many gold coins. He did not want anybody to know about them. One day, his wife asked, "How many gold coins do we have?"

After pausing a moment, he replied, "Well! If I divide the coins into two unequal numbers, then 27 times the difference between the two numbers equals the difference between the squares of the two numbers."

The wife looked puzzled. Can you help the merchant's wife by finding out how many gold coins they have?
