The Drake Equation Introduction: The Drake Equation is an elaboration of the Principle of Mediocrity; an expression that determines the probability of the discovery of extraterrestrial life within the entirety of the unknown universe. This equation combines the things science knows and does not know to come to the equivalent of N, if N is the number of intelligent species in the universe that are communicating amongst each other right now. The Principle of Mediocrity is essentially the assumption of similarity throughout the universe, pertaining to this solar system being the original copy. It allows for scientists to obtain the physiological position using the knowledge previously discovered about the Milky Way and Earth, and…
This brings up the problem known as the Fermi Paradox. This basically states that if the likelihood of intelligent life existing is so high then how come we have yet to come in contact or find proof? This lack of contact is sometimes referred to as “The Great Silence.” Many have tried to come up with solutions to this paradox and some of them definitely seem plausible. One of the obvious ones is that the Drake Equation is completely wrong. However, one of the bigger theories out there is known…
absence of evidence. Considering the age and size of the galaxy, there should be remains of long abandoned settlements, if not other life forms themselves. Despite being unsubstantiated, there still exists a number of hopeful probability estimates for the existence of alien civilizations. One source of these estimates is the Drake equation, created by Frank Drake of SETI, in which the number of civilizations capable of communication is derived…
An existing Type III galaxy could easily colonize the galaxy. Nevertheless, with no physical relics, chemical traces, or biological influences suggest the existence of any alternate life form, many may assume that there is not intelligent life beyond Earth. Beyond the Drake Equation and much speculation from the scientific world, no evidence suggests that extraterrestrials have visited Earth or have attempted communication. Without any evidence, accordingly, scientists assume that the resolution…
Does life exist elsewhere in the universe? — One of the most fascinating and compelling questions, whose answer has eluded us since the moment we learnt about the cosmos. It could in fact help us understand our own existence. There are several probabilistic arguments that not only try to show the existence of life, but also the existence of communicative civilisations. Frank Drake formulated the Drake equation one of the most famous one of these models. Rather than evaluate and quantify the…
Who doesn’t like to count stars at night? Especially a child, when he/she looks at the sky for the first time, his/her heart gets filled with many questions. Every time they learn something new, they come up with even more and more questions. Can you recall how many times you experienced something like this when you were a child? All the questions you wondered if they were true. I can recall my experiences from the past, looking at the night sky, I always wondered if there’s someone living…
were a way for professors around the world to teach their classes online for free. Like most others, my thoughts on online education mostly revolved around second-rate scams and suspicious for-profit institutions (I’m looking at you, DeVry). However, curiosity got ahold of me, and I quickly signed up for several courses. As it turned out, these courses were structured similarly to college classes; they consisted of weekly video lectures and a forum for collaboration between the tens…
This is where they began to know a little about each other and how they all got in to Princeton. After meeting and taking to one another Nash starts to walk to his dorm. As John got to his dorm, he looks around and decides to move his desk to the window. Then a guy name Charles Herman walks into the dorm and introduce himself as his roommate. Charles came in the dorm like he was some kind of a drunk person but he was not drunk. After that, John started to write mathematical equation on his…
M is the resultant internal bending moment calculated about the neutral axis of the cross section, y in this case is the thickness of the beam divided by two, and I is the moment of inertia of the cross-sectional area about the neutral axis [4]. The final equation is, Equation 5 is utilized to calculate the deflection δ of the cantilevered beam at x = L when a load is applied at a point. Since we would not applying a specific load but knowing the displacement we solved this equation for P. There…
deduce the equation landing position of the ball thrown by the robotic arm stand. We must create the equations in terms of the radius, height, arm rotation speed, and release angle. The equations must be made with those variables because, those variables are what can change where the ball will land in the cup, and will make the equation more useful to the client. To make sure the equation will remain accurate we have to keep track of all the units throughout the process. Knowing that all…
