Hypotheses In comparison to students who simply learn the features of 4 diagnostic categories, students who learn a causal explanation will: (a) recognise words describing encapsulated knowledge more accurately and (b) maintain or improve diagnostic performance under speeded conditions. In the present paper we show that students who learn causal explanations have a more coherent understanding of the relation between diseases and clinical features which, in turn, influences recognition of words or phrases describing вЂencapsulated knowledgeвЂ™ and the ability to maintain performance under speeded conditions. Schmidt has postulated that expert clinicians maintain this knowledge in вЂencapsulatedвЂ™ form, indexed by words or phrases describing the processes. Woods, Nicole N Howey, Elizabeth H A Brooks, Lee R Norman, Geoffrey RД«ackground The role of basic science, which provides causal explanations for clinical phenomena in medical education, is poorly understood. The speed of light, of course, is just one of many constants in the universe, like gravity, the specific charges and masses of the fundamental particles, quantum effects, and the list goes on.ДЄ whole handful of very specific constants that if they were just a little bit different, we would never exist.Speed kills? Speed, accuracy, encapsulations and causal understanding Speed kills? Speed, accuracy, encapsulations and causal understanding Because then we could see all the way back to the big bang. Cause and effect wouldnвЂ™t exist.Д«ut if the speed of light were slower, that might be even cooler. Time and space wouldnвЂ™t exist because all things communicate with each other instantaneously.

Because matter is made of energy, it would take infinite energy to create any mass. What if Galileo was right and the speed is infinite? See, quantum field theory claims that empty space is actually not empty at all but filled with quantum fluctuations and virtual particles popping in and out of existence.ДЄnd two different teams of researchers have calculated c using electromagnetic properties of the quantum vacuum, so it could be that the quantum foam of virtual particles and fluctuations may be slowing the speed of light.Д«ut what if the speed of light wasnвЂ™t the speed of light? It says that the speed of light is actually caused by quantum vacuum fluctuations. Now there is another theory thatвЂ™s a little controversial but starting to gain some ground. So when you look at a star at night, that massless photon might have traveled a million light-years to reach you, but its experience was instantaneous. So really, that video I talked about earlier is all wrong, from the perspective of the photon, that journey would have occurred instantly. Particles that must travel at the speed of light and because they are traveling at the speed of light, time stands still from its point of view. Nothing that has mass can go the speed of light.Д«ut if you are massless, you can only go the speed of light, because you have no speed impediments.

The other prediction that supports a speed limit is the idea that inertia increases as velocity approaches the speed of light. The speed of light is the speed of causality.

And that would break causality.Д®ffect would precede cause, which is impossible. So if you were able to travel faster than light through spacetime, time itself would actually flip. And if you were to go the speed of light, time would stop altogether. 299,792 kilometers per second.Д®instein was able to prove through his theory of special relativity that the closer you get to the speed of light, the more time slows down for a person in that relative frame. James Clerk Maxwell was the genius who first described the properties of electromagnetism into physics equations.ДЇrom these equations, we can calculate the speed of light. So weвЂ™re really talking about the speed of electromagnetism. So when we talk about the speed of light, the first thing to remember is that light is just a sliver of the entire electromagnetic spectrum, ranging from gamma rays to radio waves. You may be familiar with the speed of light, but the reason it exists and how we discovered it is pretty fascinating.
