I wasn't disagreeing with you Mordred; just trying to relate unitarity to the BH information paradox, as it pertains to the OP, in terms Airbrush would understand, without taking an advanced course in QM.

This is just 'wordology' Airbrush. Similar to finding number 'patterns' on numerology. You would make a great conspiracy theorist 🙂 .

Whoah! That is 'rough and gritty'. Unitarity simply means that the measured state of a system can be related to previous states by a unitary operator. Thus QM implies that information cannot be lost through time evolution of states. Not even beyond the Event Horizon of a BH.

I made no assumptions. He stated I haven't taken a keyboard apart since they became 'disposable'. Long ago the key matrix was decoded by a microcontroller ( usually i8748 ) and its internal ROM would output ASCII codes. Until the early 90s I cut my computing teeth on Sinclair machines, Big Board CP/M, Atari STs and Amigas ( still tinker with ST and Amiga hardware because non surface mount components are easier to see/work on). Built my first PCs in '94 when the Win95 hoopla started. Three Pentium 166 machines with 32MB RAM, 2GB mechanical drives, and a 1st generation ATI 3D 'decelerator'. One for me, one for my brother's 5 yo son, and one for my sister's 6 yo son and 4 yo daughter ( who now won't go near anything that isn't Apple/Mac )

He was already 'all in' on being an asshole.

The keyboard is laid out as a matrix of intersecting lines. Hitting the 'R' key closes a contact between the row and column lines and a value is sent , in hexadecimal format, to an 8 bit processor in the keyboard, which then serializes the ASCII code for 'R' and sends it, through a USB channel to the computer's USB decoder which converts it back to parallel binary data again, so it can be read by the CPU. No processing is to be done on this data, so it is placed in the common area of main memory ( RAM ) where it can also be accessed by the display processor. The display processor changes the binary data into a bit map and places it in the display buffer, adding any attributes that may be required for the specific windows display environment ( color/intensity ), and the display buffer is then serialized again to be output to a monitor, along an HDMI channel, to be 'drawn' on the LED/transistors of the screen matrix, one row at a time, until the whole screen is 'painted' at a refresh rate of 120 Hz, and the letter 'R' is displayed in that window. The Operating system, Win10 in this case, is responsible for setting aside the part of main memory that corresponds to the display buffer, and the particular subset that is the contents of that window. Do you really think you understand it better now ? Unless you learn the basics, you don't have a chance of understanding.

Further to the points Mordred brought up, is anyone even using the EFE to analyze galaxy rotation curves ? The discrepancy is readily evident when using the Newtonian model for gravity ( which I realize is also an approximation so possibly subject to similar errors ). As a matter of fact, one proposed solution is MOdified Newtonian Dynamics ( MOND ), but as you state, that has significant issues. And it's not because Non-Idealized General Relativistic Dynamics (NIGRD ) doesn't roll off the tongue as easily 😄 .

He's already been forced to make bad moves, such as picking J D Vance for a running mate. Maybe he can 'zwischenzug' by getting shot again and gaining some sympathy votes.

Depends. I don't work in the computer industry, nor have ever taken any computer courses. I did take a half course in Electronics for Physics over 40 years ago, and did some programming , mostly FORTRAN, Basic, Pascal, Forth, C, and some Z80 assembly, but don't anymore, so I could be considered a 'layman'. And I understand that definition. Or did you think the definition was going to tell you everything you need to know about computers ?

Unfortunately that violates a quantum mechanical property called unitarity, and is at the heart of the BH information paradox.

Art has value in two ways 1 ) It makes you feel good because you can interpret it to fit your mood. 2 ) You can boast that you can spend that kind of money on something and pretend it makes you feel good.

It's several months till the election and a little early ( or is it already too late ) to start underestimating the stupidity of some Americans.

Money and wealth don't necessarily make people evil. But it is much easier for unscrupulous, corrupt ,evil people to gain wealth and riches. The two sets definitely overlap significantly, but it is hard to say which causes which.

It is extremely irritating when the ads pop-up at the most inopportune times. If you go to a different tab to check/copy a link or something, an ad will usually pop-up, and you have to re-open the editor to retrieve your unfinished post. Another irritation that has happened at least twice now, when attempting to submit a post an ad will pop up, you cancel the ad and re-submit the post as it doesn't seem to have posted, and you end up with a doubled up single post, necessitating an edit to remove the second of the double. Is someone working on these issues, or do we simply have to live with all the ads between posts, plus these irritating pop-ups ? I'm sure I, and many others, are so irritated by the pop-ups that we will make it a point to never consider any of the items/services advertised in this manner; that makes them useless, because if we don't, who else can possibly be targeted by these ads ?

The processor in your computer 'reads' the incoming serial data stream that your Wi-Fi adaptor captures, and it performs some mathematical operations on to make it understandable as 64 bit long words of instructions or data, before placing it to a location in main memory. Thr display processor then takes over and reads these instructions or data, and manipulates the data ( according to the instructions ) to transform it into intensity and color information into its own memory called the frame buffer, and then outputs it sequentially to each pixel on the screen to form an image which you can read on your monitor. Any more detail than this and you'll need to take some electronics courses, and learn about transistors and gates, various types of memory ( volatile and 'permanent' types ), ALUs, their registers and how they manipulate binary coded bytes/words/long words, and how modern bit-mapped graphics displays are handled by massively paralleled simple processors for raster operations as well as mapping, rendering, shading and even ray tracing.

Never thought of it that way. I do remember the old saying "No one ever got rich by doing an honest day's work"

Whoa! Maybe if you'd put as much thought into your proposed propulsion system you'd realize why it cannot work. So you've tried this elsewhere and gotten the same response ? I guess some people never learn. Incidentally, I hane never tried to build a perpetual motion machine; I know it is impossible. And not for the reasons you state. Basic physical laws, tried and tested, for hundreds of years, such as momentum conservation, and in my example's case, that gravity is a conservative force, and whether you take a circular route or a direct vertical route to the same height, you do the same work. Then again, the equivalence principle relates gravity and acceleration, and since propulsion involves accelerating a mass in one direction to achieve a 'thrust' in the opposing direction, the two examples can be related. If you had any knowledge of Physics you'd understand that. But I guess all the brilliant engineers at NASA, Arianespace, all the major defense contractors, and even private ones such as SpaceX must have exhausted you when you tried explaining the 'details' to them. I didn't bother reading the rest of your long-winded post; you've wasted enough of you own time and I don't wish to waste anymore of mine.

It heals and does only superficial damage. However, it stings like a son of a b*tch.

Nixon's biggest fault is that he got caught doing what every other President/politician does ( except maybe J Carter ). I love this picture of him in the Kitchen with N Khrushchev, when he was vice-President to Eisenhower I I'm sure D Trump ( or E Musk ) would be kissing his ass, not poking him in the chest. Kitchen Debate - Wikipedia

With his new found 'Christianity and family values', along with his so called business acumen, maybe he's positioning himself for the next Republican messiah, after D Trump fails.

Yeah. I once built a perpetual motion machine using the same principle. Two reservoirs connected by a tube and mounted on a large wheel, with one reservoir, the top one, filled with water. As the top reservoir empties into the bottom one through the tube, it passes through a generator to make electricity. When all the water has emptied into the bottom reservoir, we simply spin the wheel, and the bottom reservoir goes to the top, beginning the process all over again, and generating more electricity. Needless to say, IT DID NOT WORK ! You can draw all the fancy pictures you want, but I suggest learning a little Physics first. And not from ChatGPT or any other so-called AI.

I thought it was going to be a trick question, as the velocity at the highest point is 0. The acceleration, other than at the launch, is always -g, downwards. ( depending on convention, an upward moving body has negative acceleration, while, if falling, a positive acceleration )

There is water on Mars, but always assumed it would be only in frozen form, like at the poles. Liquid water at depths of 6-12 miles, means Mars' core provides significant heating, and possible habitable underground zones. And we don't need Doug Quaid to go start the huge nuclear reactor to melt the underground ice and provide an atmosphere and seas to make Mars habitable. If I 'totally recall' correctly ...

All are figments of the brain, under stress by the circumstances. The brain often 'fills in' missing information with what is stored in familiar neural pathways. Nobody sees the blind spot each eyeball has ( where optic nerve connects to retina ), even though every eyeball has one, because the brain makes stuff up for you to see ( and does so pretty accurately ). It is people who place significance and importance on these NDEs and OBEs that are deluded.

What does it matter ? His beliefs had nothing to do with science, which is evidence based for any good scientist. Are you hoping that if a 'smart' man can hold those beliefs, it is a validation of your belief system ?
