Scientists at CERN have been throwing world-class technology and researchers at a simple question: what makes clouds form? A new paper from the so-called CLOUD group has unearthed two important discoveries concerning the effects of ionizing radiation and amine vapors on cloud formation.
Question by lauren_the_cheerbum: A description of the Scientific Theory of the Origin of Life. 10 pts for best answer?
A description of the Scientific Theory of the Origin of Life.
A description of why you support or refute the scientific theory of life.
A description of your theory of how life began on earth.
Answer by magnetz121
I heard that intense heat created amino acids and they formed to create cellular structures.
I think that is a highly plausable theory because it has been proven that this can happen.
Another possibility is that alien terraforming experimants created life on earth so we would thrive and they could come back and consume all organic life on earth.
What do you think? Answer below!
Considering the usual subject matter of The Big Bang Theory it’s a bit bizarre that the first couple of seasons weren’t already available in high definition, but Warner Home Video has now announced they will be released on Blu-ray July 10th. While later seasons have already seen Blu-ray releases, those looking to start back at the beginning for Leonard, Sheldon, Penny and the rest of the crew had been stuck with DVDs. Assuming you’re a fan of CBS’ comedy series, you can preorder each Blu-ray / DVD combo release now, priced at $ 23.99 for the first season and $ 54.97 for the longer second season. Of course, what we’re really wondering is what this means for other orphaned releases that only have some or none of their seasons available on Blu-ray as studios have shifted strategies, we’re still waiting for How I Met Your Mother season one. Drop a note about any other shows you’re following that have holes in their HD releases in the comments below, or just check out a video clip of the show with the canned laughter cut out — it’s… different.
Question by : What is Control theory and feedback in robotics?
can you please explain clearly the concepts of feedback and control theory in robotics? as much detail as possible please. Leave nothing out
Answer by R G
Feedback is usually the input minus the output (input after a response function) so the robot get a error and gets new values to try to minimize I-O

String Theory: Guitar And Piano Chords In Parallel.
In one small win for Einstein, one giant win for mankind, scientists at the Niels Bohr Institute have proved his General Theory of Relativity on a cosmic scale through their research of large galaxy clusters. Accordingly, the clusters — which are the largest known gravity-bound objects — have such a strong pull that they should cause light to “redshift,” or proportionally increase in wavelength, shifting towards the red end of the visible spectrum. To test it, researchers measured beams from 8,000 clusters, revealing that they do indeed cause a change in light’s wavelength, supporting Einstein’s theory to a T. One good turn deserves another, right Albert? Armchair cosmologists can hop on over to the source link to learn more.
CERN scientists discover particle traveling faster than the speed of light, Einstein theory threatened
It ain’t over till the LHC says so, which is why researchers at CERN are opening up their most recent OPERA experiment to the scientific community before officially releasing its findings. Why, you ask? Because the experiment could shatter one of the fundamentals of physics — Einstein’s theory of special relativity, which says nothing in the universe can travel faster than the speed of light. While studying neutrino oscillations — where particles shift from one type of subatomic particle (muon-neutrinos) to another (tau-neutrinos) — scientists clocked a beam of muon-neutrinos outpacing the aforesaid ray of light by 60 nanoseconds. Calling the result “crazy,” lead scientist Antonio Ereditato published the findings online, hoping to attract the attention of others who might shed some light on what it all means. We’re not expecting a conclusive answer any time soon, but budding whiz-kids can get educated in the links below.
The iPhone 5 case we published first has completely stolen the show for the last week or so. To corroborate it, Apple.Pro has now posted an image of back cover of the White iPhone 5 which clearly shows two different holes. One is for Camera and other for possible camera flash. There is however no authentic […]
Theory of Applied Robotics: Kinematics, Dynamics, and Control 2E is appropriate for courses in robotics that emphasize kinematics, dynamics, and control.
The contents of this book are presented at a theoretical-practical level. It explains robotics concepts in detail, concentrating on their practical use. Related theorems and formal proofs are provided, as are real-life applications. Students, researchers, and practicing engineers alike will appreciate this user-friendly presentation of a wealth of robotics topics, most notably orientation, velocity, and forward kinematics.
The second edition includes updated and expanded exercise sets and problems, new coverage includes, Components and Mechanisms of a Robotic Systems with actuators, sensors and controllers and updated and expanded material on Kinematics including geometric kinematics, Derivative Kinematics, velocity kinematics, and new coverage on sensing and control including position sensors, speed sensors and acceleration sensors.
