  1. I disagree. Democrats called for investigations. They called for witnesses. Republicans tried to and did shutdown investigations. They cancelled the FBI probe. Democrats didn’t want to give Kavenaugh a lifetime seat on the bench because of the way he responded to the claims and how he comported himself. What are Democrats doing with Biden? Saying the claim must be taken seriously. They’re asking for it to be investigated. They’re watching how Biden responds to the allegations. Its an easy talking point, sure, but I’m not seeing the hypocrisy and double standard you seem to see.

  2. Really ? 1apple - 1apple =0 You had one apple, and you ate it; now you have none. What action and reaction are you ascribing to simple math operations ? ( unless you mean eating is the action, and going to the toilet is the reaction ? )

  3. Effective mass is not the same as inertial mass. It is the mass the electron 'appears' to have when subjected to certain fields/forces. See here... https://en.wikipedia.org/wiki/Effective_mass_(solid-state_physics) The earliest ( easiest ? ) way quantum tunneling was described to me ( back in 2nd year ) is if you consider the wave nature of the electron as described by a wave packet. If that wave packet is 'wider' than the potential barrier, then some part of the wave packet will lie outside the barrier. IOW there is a finite probability of finding the electron outside the barrier. ( and as simplistic as this is, it still assumes you are familiar with some aspects of QM )

  4. Missing the point is what makes life interesting. The journey trumps the destination. Plenty of time for contentment when we are dead,although excessive dissatisfaction is a curse.

  5. There is no difference between the mathematician's definition of 'compact' and the physicist's. Indeed this is explicitly stated at the beginning of your link. note the sentence which begins "the methods of compactification are various....." Here you are talking about compactifying a group. Nothing wrong with that , not all sets are groups though mathematically the meaning is the same. But mathematically 'compact' and 'compactification' is about sets. We like compact because it allows us to use general theorems like the Heine-Borel theorem as justification for the mathematics of our functions and operations on them eg calculus. We like compact surfaces and manifolds as they keep sets and their coverings under control. The same ideas are also used by Engineers, as this extract from "Introduction to Differential Geometry for Engineers by Doolin and Martin" shows. Note their comment about research papers!

  6. You should pack entire folder to zip and attach in reply. Not copy'n'paste code.. Anyway. Here is how it looks on my Firefox: After changing error mentioned by Strange in line 12 to: </h1><br><img src="ian.jpg" height="370" width="300"> and changing line in CSS file to: .top{color:yellow;} How it should looks like? How it looks like on your machine/browser? There is yet another error... It requires url( 'filename' ); See how to use this property properly: https://www.w3schools.com/cssref/pr_background-image.asp

  8. Right, acceleration should be the main focus. The video shows the jet tracking the UFO, and then suddenly the object accelerates out of frame at such a speed that the jets could not keep up with it. According to David Fravor, the object practically disappeared in front of their eyes, reappearing a few seconds later 60 miles away after the Princeton picked it back up on radar. However, if there were multiple objects in that AO then that would explain the object "reappearing" on the radar 60 miles away. Here is an excerpt from the Popular Mechanics article: The second object suddenly rose up and flew towards the Super Hornets, with one pilot. Commander David Fravor, saying it appeared it was rising up to meet him. The Hornet turned towards the object to meet it and the object peeled away, accelerating, “like nothing I’ve ever seen,” Fravor later said. The Super Hornets conferred with the USS Princeton and were vectored to a CAP point 60 miles away. Within seconds, the pilots were told by the Princeton that radar had picked up the object already at the CAP point. By the time the Super Hornets arrived however the object had already disappeared. Source: https://www.popularmechanics.com/military/a14456936/that-time-the-us-navy-had-a-close-encounter-with-a-ufo/ ----------------------------------------------- Another point of focus: the USO (Unidentified Swimming Object) aspect. There are several interesting details about the sighting here. For one, there were clearly two unidentified objects. The first was a large underwater object that was “much larger than a submarine.” For reference, the U.S. Virginia-class nuclear attack submarines are 377 feet long. The object also had some passing resemblance to a “downed airliner.” This was technically a USO, or unidentified swimming object. Although much rarer than UFOs, such craft have been sighted over the years. I find this interesting, because similar to UAVs (Unmanned Aerial Vehicles), the military has been working on USOs for sometime also: Full-sized, staffed ships and other sea platform cannot perform safely in all Navy missions in near-shore, or littoral waters. These missions include mine location and avoidance as well as remote surveillance. In 1988, a joint DARPA/Navy Unmanned Undersea Vehicle (UUV) Program was initiated, with the goal of demonstrating that UUVs could meet specific Navy mission requirements. The program started with a memorandum of agreement between DARPA and the Navy that specified the design and fabrication of test-bed autonomous vehicles, the independent development of mission packages, and their subsequent integration. The Navy initially pursued a submarine-launched UUV that would either guide the submarine through an area that might be mined or search an area for mines. When the Cold War ended, however, the Navy revised the program with the objective of developing a tethered shallow-water mine reconnaissance vehicle for littoral warfare. The work in the UUV led to many follow-on projects, along with a range of technology developments. Even as the Agency enters its seventh decade, UUV R&D remains part of its portfolio. Source: https://www.darpa.mil/about-us/timeline/unmanned-undersea-vehicle-a So, perhaps this weapons system was a combination of USOs/UUVs and UAVs working in some kind of CODE organzation. The UAV would rendezvous with the USO/UUV into a battle group and then launch back out on mission, similar to the photo I posted above where the UAVs are grouped in formation just above the water's surface. This would correspond to what Fravor saw: a smaller "Tic Tac" (the UAV) launched from a much larger submarine like craft.

  9. Don't know if determinism will survive Quantum Gravity. But currently Quantum theory and GR are kicking and screaming trying to avoid unification. As Batman said... "My parents taught me a different lesson, dying in the gutter for no reason at all... They taught me the world only makes sense if you force it to.” What... I'm not gonna believe Batman ?

  10. What I am saying is that once we establish a manufacturing base in space that uses in situ materials the economics of space flight will change. Right now everything has to be dragged out of the Earth's gravity well, the economics of that is truly staggering but building a brobdingnagian object in space using materials already there will cut costs considerably. Perhaps I dumbed down the concept a bit, I am trying to avoid as much typing as possible since I almost sliced off my thumb a few days ago. Yet trying to type fast to avoid the boss, my wife my wife hits me in the head with a ball bat, plastic thank god, when she catches me... Actually, if you on a slow boat fuel requirements are smaller and a solar sail could be used to slow down at the end. I am honestly unaware of where I made any claims about speed, please let me where and I'll either defend to admit i was wrong. See above... An actual dyson sphere consisting of a solid sphere covering the sun violates all known and hypothetical physics... https://www.space.com/38031-how-to-build-a-dyson-swarm.html Sending small objects in orbit to build larger structures is currently being done, the international space station is an example. ???? I was answering the idea that physics prevent star travel when in fact it does not.We currently have two space craft on the way to doing it. Time and energy are what it's all about, which do you have the most of? "To say anything is impossible you must point out something about it that supports that idea. Neither space travel, dyson swarms, O'Neil cylinders, or star travel has any impossible or even yet to be invented aspects but controlled fusion would be a nice touch for star travel.... If you did not say these things were impossible I apologize Please show me were I am tap dancing around anything? Building things in microgravity redefine scale... I cannot find where I claimed much of the stuff you are asking about,sadly there appears to no way to tell what number post I said these things, I feel overwhelmed swansonT but I will say,and please take note of this I am hear to learn not to convince people of things not true but answering this post makes me feel like you have mistaken I said either out of context or attributed to me something someone else said. I need help here, please show where I claimed these things. I have labeled them with question marks for your benifit...

  11. If you can look up "meme" on wikipedia, maybe you can also look up "quantum realm"?
