The Drake Equation

Image
Ever heard of the Drake equation? Devised by Dr. Francis Drake in 1960, the equation estimates the number of extraterrestrial civilizations in our galaxy with which we might come into contact. The main purpose of the equation is to allow scientists to quantify the factors that determine the number of such extraterrestrial civilizations. The Drake equation states that: where: N is the number of civilizations in our galaxy with which communication might be possible; and R * is the average rate of star formation per year in our galaxy f p is the fraction of those stars that have planets n e is the average number of planets that can potentially support life per star that has planets f ℓ is the fraction of the above that actually go on to develop life at some point f i is the fraction of the above that actually go on to develop intelligent life f c is the fraction of civilizations that develop a technology that releases detectable signs of their existence into space L is the

Harnessing Energy from Speed Bumps

Here is an interesting post on the use of special speed bumps to harness, convert and store energy from braking cars only to be released back to the grid. This seems like an interesting innovation that holds promise for the environment. I have always hated speed bumps with a vengeance. Next time I work the brakes on these bad boys however, I can take comfort in helping the world. Hopefully, this will become mainstream some day. -PTS

A Prelude to the Origin of Life on Earth

I was looking to do a deep dive into the origin of life on Earth, a topic that has always intrigued me. Two main schools of thoughts today generally revolve around creationism or abiogenisis. Before engaging in serious research however, I came across this interesting post . Scientists theorize that Earth's oceans may have been 'delivered' by comets during massive collisions. It was comets and not asteroids because of specific amounts of iridium found in Greenland's rocks. In case you are wondering, here are the common differences between comets and asteroids: Comets display comas and tails due to sublimation of water and ejection of dust particles from solar radiation. Comets have more eliptical orbits than asteroids around the sun. Comets may become asteroids when they run out of watery particles. This article is exciting because it opens up a whole new perspective on the origin of life. It is commonly believed that life first formed in bodies of water. Is it pos

Finally, Something Good from Global Warming

The words global warming are often frowned upon. Amid the negative press, can this article help turn the tide? Scientists claim that climatic changes due to global warming has seen increased rainfall in parts of the Sahara Desert. More islands of green are beginning to show, especially in the southern borders. In time, these areas can be reclaimed for agricultural activities. So why the phenomenon? One theory suggests warmer air being able to hold more moisture, which in turn creates more precipitation. However, it is too early to cast your vote. There are other competing climate models that predict decreased rainfall, pointing the finger at global warming. The split is virtually a dead heat. - PTS
