Paul Sutter has a way with words. In a Space. For the precocious hunter of off-Earth life, the Drake equation is the ever-ready, go-to toolkit for estimating just how not lonely humans are in the Milky Way galaxy. An equation needs certainty, Sutter argues. Without some grasp on precision with the factors in the equation, it becomes useless, no better than a wild guess. The equations of physics deal with measurable factors that can be ascertained often to many decimal points of precision. The equation starts with some straightforward concepts, such as the rate of star formation and the fraction of stars hosting planets. But it quickly moves into tricky terrain , asking for numbers like what fraction of those planets that could host life actually end up evolving intelligent species and what fraction of those planets blast out friendly signals into the cosmos, inviting us Earthlings to a nice little chat.

The Drake Equation is a formula for the number of developed civilisations in our galaxy, the Milky Way. This number is determined by seven factors. Some are known with good accuracy but the values of most are quite uncertain. It is a simple equation comprising seven terms multiplied together see illustration.
There are no exponentials, no power laws and no logarithms; the equation is linear in each of its factors. All terms are equally important, and the overall uncertainty is dominated by the most uncertain terms. This meeting was to investigate the possibility of detecting intelligent life in the Milky Way.

I have decided to turn the preparation that I did for that panel, and notes taken during the panel discussion, into a tutorial on the Drake Equation. Dubbed Project Ozma, for a period of 6 hours a day for four months the NRAO radio telescope listens for radio signals of intelligent origin. None are found. Within a year a meeting is hosted in Green Bank to explore the issue of extraterrestrial intelligence. Frank Drake needed to come up with an agenda for the meeting in order to provide some structure to the discussion.
To serve as an agenda, he devises the Drake Equation.

OK, so a couple of physicists walk into a bar. Just kidding. They’re not at a bar. They’re at a school. Scientists in training. I’m sure this story seems strange to you, but to me, it was just– you know, this was just like another day in the physics world.

Understand the power of compound interest? I firmly believe that those who are competent with maths are more likely to have the skills to be on top of their personal finances. This could be calculating your correct pay, comparing the cost of mobile phone contracts or how much interest you will be charged on your credit card this is where knowing the difference between APR and AER comes in handy. Numbers are the language in which our finances are expressed. Maths is a tool for us to understand the world.
Within the financial world, numbers can be used to trick consumers but if we understand the basic concepts we are in a position to make a better judgment. As many of you will know from my University Challenge days, I am a sucker for a quiz show. Yes, 10 points to you if you guessed Napoleon Bonaparte. I genuinely believe maths can help us understand the world around us.

Area 51 is a military training range at Groom Lake, Nevada, and for decades has been at the centre of a conspiracy theory that the US government is hiding evidence of extraterrestrials visiting the Earth.
The idea that aliens exist has been around as long as people have understood that the Earth is not the centre of the universe.

Unlike those who cannot find a girlfriend in any way conceivable, which makes them wanking losers. Everyone who ever finds a girlfriend at all does so through social networking.
The Drake equation was developed in by American astronomer Frank Drake, as a method for calculating the probability of finding extrasolar life in our galaxy. The number of intelligent civilizations N is calculated by first estimating the formation rate of stars r and then multiplying by the fraction of those stars that have planets and by the number of habitable planets per system.
This brings up the concept of the habitable zone of a star. The habitable zone is defined as the region where the temperature is right for liquid water to exist on the surface of a terrestrial planet. As seen in the illustration above, massive, hot stars have habitable zones that are much farther away from the star than smaller, cooler stars.
Drake’s equation then multiplies the number of planets in the habitable zones of stars by the fraction of those planets where life actually arises.
to convolve probability distributions instead. • Implicit certainty in use of Drake equation produces problematic conclusions.
