![]() So in the black hole example, all of the particles that have entered the black hole have physical properties like velocity, momentum, spin, and others. At its most basic, information in physics might be thought of as all of the details that describe some system. There are entire textbooks on the subject! And it's an area of science and math that is still evolving. When the word "information" is used, in this context, to what does it refer? I'm sure I'm not asking the question correctly, but information has a different meaning depending on the discipline using it. In the description, this phrase: ".the information held by a black hole." The Martians hold a lot of contempt for Earthers on this matter.ĭergolem wrote:This is the first APOD I've come across in a long time that I'm having a hard time wrapping my head around. Like in the opening credits for The Expanse where they're just putting walls around the Statue of Liberty and Manhattan. I feel like most of the developed nations have a lot of buffering and can deal with certain things for quite a long time. The connection between smoking and cancer has a high impact in a single human lifetime while climate change is going to take generations to have the same sort of impact, at least for the biggest contributors. I'm afraid it's going to work a lot longer with climate change. AHI was the main driver of the "smoking isn't dangerous" pseudoscience. It worked for a few decades with smoking. They can be dead wrong about everything they say, but if it causes people to doubt, they still win. Not that any of this matters to a group of people whose strategy is comprised entirely of doubt. Outside a given subject area, it's the most important method for non-experts to know what they should take as likely truth. Within any given subject area, consensus is an important tool for focusing the direction that researchers devote their attention. And they completely misunderstand consensus. ![]() Skepticism is simply a necessary quality for a scientist. (Let's make American science great again by making it dependent upon the generosity of wealthy Americans who want their names on things.) All they could do was to pat themselves on the back for " being truly scientific" by disagreeing among themselves on whether the government should be in the business of supporting science at all. The American Heritage Institute panelists seemed to have little to no interest in doing any of these things. 1) putting forth a reasoned hypothesis ( e.g., man made CO 2 will melt the Arctic Ocean)Ģ) collecting data to test that hypothesisģ) analyzing the data in an unbiased fashionĤ) and coming up with a reasoned conclusion.There the AHI panel "argued" that scientific consensus (on global warming & Darwinian evolution in particular) was basically a contradiction in terms since science is primarily about skepticism. After it was over C-SPAN (for balance) replayed Wednesday's panel discussion by the conservative American Heritage Institute. The weather being what it was yesterday I decided to stay home and watch 'The March for Science' on C-SPAN. Whenever I see this stereogram, it brings to mind Russell's teapot. ![]() Beware, other people looking at the featured image may not claim to see 3 x 1065 bits - they might claim to see a teapot. The term " holographic" arises from a hologram analogy where three-dimension images are created by projecting light though a flat screen. It can arise from generalizations from seemingly distant speculation that the information held by a black hole is determined not by its enclosed volume but by the surface area of its event horizon. The limit was first postulated by physicist Gerard 't Hooft in 1993. The principle derives from the idea that the Planck length, the length scale where quantum mechanics begins to dominate classical gravity, is one side of an area that can hold only about one bit of information. Therefore, counter-intuitively, the information content inside a room depends not on the volume of the room but on the area of the bounding walls. The Holographic Principle, yet unproven, states that there is a maximum amount of information content held by regions adjacent to any surface. ![]() Explanation: Is this picture worth a thousand words? According to the Holographic Principle, the most information you can get from this image is about 3 x 1065 bits for a normal sized computer monitor. ![]()
