Breakthroughs, discoveries, and DIY tips sent every weekday. As any diligent stargazer knows, mid-summer means one thing: the Perseids! This meteor shower hits its peak on August 12 this year, and while that date is inconveniently close to that of this month's full moon, there should still be plenty of meteors on show for those who choose their time and location with care. As another long summer day has finally receded into another summer night, look east. If the sky is clear, you might well spy the Summer Triangle.

Legend has a prominent tale about a man who caught a large fish and kept it in a big tank filled with a lot of tiny fish. Over a few days, he observed that it was very easy for the big fish to catch the smaller ones and eat them. In due course of time, he partitioned the tank with a glass, in such a way that the big fish remains on one side of the glass, and the smaller ones on the other side. He noticed that the big fish tried hard over the first few days to catch its prey but failed to do so due to a glass partition. The man eventually removed the glass partition after a week and noticed that the big fish had stopped trying to hunt its prey.
