There is no exception to this rule. Example: "Newton's laws" is not a physical quantity therefore "Newton's laws" is metaphysics and does not belong to scientific physics. Laws, principles, axioms, definitions, conjectures and similar philosophical stuff are independent of ... http://globalpioneering.com/wp02/physics-and-metaphysics/ In Definition 5 Newton defines a new word to describe a new species of force he just invented: centripetal force. Centripetal force is a force that seeks a center. Newton gives four examples of this force: Terrestrial "heaviness" with which bodies tend to the center of the Earth; iron ... http://globalpioneering.com/wp02/how-did-newton-spin-rotation-into-orbits/ Not Even Wrong points to a paper by the string theorist Moataz Emam that asks the question So what will you do if string theory is wrong? As an answer he suggests that physics may divest itself from string theory and create a new academic department equidistant from physics and ... http://globalpioneering.com/wp02/what-if-string-theory-is-wrong/ A scientific principle: If a problem is independent of a term that problem is independent of that term. Example: Given f(x0, x1), then, the problem modeled by f(x0,x1) is independent of any term xn > x1. Question: This principle is generally accepted and used in physics. For instance orbital motion is described by ... http://globalpioneering.com/wp02/does-physics-admit-casuistry/ Humans have a unique ability to create environments that are depressing, writes John Baez. Some are melancholy, unloved, like a dimly lit highway overpass at night covered with graffiti, or this building in Shanghai: I understand this feeling. At times I felt the same way. But unlike the holographic principle, ... http://globalpioneering.com/wp02/ugly-side-of-buildings/ Check out Peter Callesen's wonderful paper cut-outs. ((from Mathematics under microscope.)) These paper figures that come out of paper but could never fully free themselves from the background inspire us to speculate on the most fundamental philosophical question: Is there a theater of operations where phenomena happen? Or asked in ... http://globalpioneering.com/wp02/natures-maze/ Water inside a rotating sphere: I assume that the spiral shape arises because the bottom of the vortex touches the sphere? Here's a simplified geometry of the same phenomenon: This is figure 11.7: Shape of liquid surface in a rotating bucket, in Equilibrium statistical physics by Michael Plischke and Birger Bergersen. They reason ... http://globalpioneering.com/wp02/rotating-bucket-experiment/ Every important unit in physics progresses through five stages. The following process is a constant of physics and cannot be changed. 1. No unit Initially a proportionality new to physics is stated without a unit. In the 18th century physics textbooks stated "Newton's law" as 1/R2. Just like that, no unit, no ... http://globalpioneering.com/wp02/fundamental-constants-of-physics/ Is there really a distinction between a physical quantity and a non-physical quantity? Judging from the definition of physical quantity, there isn't. "Physical" means "belonging or owned by the profession of physics." If a quantity exists in the legal physics code, it is called a physical quantity. It is implied ... http://globalpioneering.com/wp02/physical-quantity/ To me F=ma is an absurd statement which is equal to Here's the derivation: F is the Newtonian force. By definition the Newtonian force acts instantaneously from a distance. Therefore, for the Newtonian force all distances are zero. As far as F is concerned radius R of any orbit is ... http://globalpioneering.com/wp02/fundamental-equation-of-physics/ Newton was a crank and a recluse and a religious bigot who spent much of his time dwelling in a self-generated fog of superstition and crankery . . . says Christopher Hitchins. ((From Not Even Wrong)) I guess Newton still had enough quality time left to orchestrate one of the ... http://globalpioneering.com/wp02/the-newtonian-occult-in-general-relativity/ Urs Schreiber in article Charges and Twisted Bundles, III: Anomalies writes: They are called “anomalies”, I’d say, because to a large extent in physics the approach is to pretend that working locally is fine – until one happens to run head-on into global issues. A mathematician might say at this point: ... http://globalpioneering.com/wp02/the-universal-localglobal-pun/ In their derivation of orbital motion physicists write down the mass m of the orbiting satellite and later cancel it and they conclude correctly that the orbit is not dependent on m, as stated on this NASA page: There is an important concept evident in all three equations – the period, ... http://globalpioneering.com/wp02/orbital-motion-and-newtons-authority/ 1. F=ma Physicists start their derivation with This statement may be meaningful to physicists but the truth is that all three terms, F, m and a, disappear during the derivation. None of these Newtonian terms enter the formula used to compute orbits. From this observation we must conclude that F, m and ... http://globalpioneering.com/wp02/physics-derivation-of-keplers-rule-from-newtons-laws/ From Dreams of Calculus - Perspectives on Mathematics Education: ((Thanks to Misha for bringing this wonderful book to my attention.)) Classical Greek or Latin formed an important part of secondary education only 50 years ago, with motivations similar to those currently used for mathematics: studies in these subjects would help ... http://globalpioneering.com/wp02/is-calculus-a-dead-language/ The ignorance or willing negligence of data types allows physicists to write absurd statements such as Physicists are very proud of the logo of the House of Newton but what does it mean to multiply two masses? It is absurd physical Type Newton In the multiplication both M and m are type Newton. ... http://globalpioneering.com/wp02/newtonian-multiplication/ I've been trying to decipher the data types of F, m and a in physicists' expression F=ma. I still do not know for certain. I believe the standard interpretation by physicists is that force F is proportional to acceleration a and mass m is the proportionality constant. Is force a physical ... http://globalpioneering.com/wp02/data-types-of-fma/ Shtetl-Optimized says: At no point did Einstein ever embrace mysticism per se. That’s another crucial difference between him and Newton . . . Einstein was practicing mysticism when he claimed to compute the radius of the ultimate reality. ((Einstein's legacy is the modern cosmic mythology called cosmology.)) Mysticism is the claim ... http://globalpioneering.com/wp02/newton-and-einstein-the-crucial-difference/ TO THE ILLUSTRIOUS MAN ALBERT EINSTEIN AND THIS HIS WORK DONE IN FIELDS OF THE MATHEMATICS AND PHYSICS A SINGLE DISTINCTION OF OUR TIME AND RACE Lo, for your gaze, the pattern of the skies!
