The intent of Israel bombing AP/Al Jazeera offices
Jews made impressive transformation.. Impressive in very bad sense.. Transformation from nation which was bulk exterminated during II world war - tragedy which aroused sympathy and compassion in hearts of people around the world.. Now they regained status of the most hated nation of the world. Impressive degradation..

Money, is it worth it?
You mix (and put them in the same bag) investment banking, enterprise banking, with classical banking ("retail banking") i.e. an institution which just collects deposits from people with money/assets, and distributes them across investors which need funds to build new businesses. A successful businessman, with good business plan (which is carefully analyzed), will have the money to pay back loan and the bank will have the money to give their deposit owners plus interest. Interest of classical bank is identical with client's interest. They both want to build a successful business that works flawlessly. The investment bank/enterprise bank is often a hidden player i.e. knows how much other players (bank clients) put into some financial instrument, and having this abnormal knowledge is/can be actively playing against them, or employee of an investment bank can play against his/her own clients, or release info to other players (typically for bribe) to give them an advantage over other players etc. Even classical banking eroded these days i.e. because bank employees are receiving premium bonus to wage for every new loan they gave. Typically regardless of quality. From point of view of bank client which received credit and pays regularly loan installments is good client. From point of view bank employee what only really matters is quantity of clients, and amount of bonuses. i.e. bank's interest is against bank employee's interest (!) and he/she can play against institution in which he or she works for (by giving loans to people who will surely have troubles pay them back) ! Bank (in good classical banking) wants to have as few as possible 'bad credits'. Bank (in extremely eroded classical banking) wants to cause bankrupt of their own clients which received loans to intercept their assets (which is often the case in US these days.. what happened in 2008/2009 was "fixed" in the most worstest way). Classical banking eroded in many ways: consumption loans. Such are bad loans since the beginning! Because they give nothing worthwhile (maybe except volatile, a few day, joy) to the client which took them. Instead, often puts them into debts and troubles. Loans for Christmas Holidays? For better food, gifts to family and friends? Absolutely silly to take and give such loans! Every year, every holiday, I hear the same advertisements of quick and cheap loans around November and December.. If you can't afford it, you should not take loans for extravagances. The economic system and banking system on this world are totally eroded. Interest rates with variable part? Client for loan should know since the first day, before taking loan, how much will have to pay at the end, and any bit more. Regardless how long it will take to pay back. Currently you can take $100 and you might end up returning $1000.. Any attempt to fix the situation e.g. return back to positive interest rates would result in complete collapse of economic system, because borrowers would not able to pay them back anymore. Borrowers (individual and corporate) who took the money (with current minimal rates) and invested in stock exchange, would have to sell stocks (the all borrowers, at the same time), and stock markets would collapse. Then, corporations with loans by themselves, which used their stocks as guarantee, would be put into trouble and forced to sell them, forced to introduce optimizations i.e. sell assets, fire employees. etc. etc. The economic and banking system in this world is a "house of cards" ...

Cryptocoins: who pays the huge energy?
I think people don't count correctly costs and energy consumption, because they concentrate just on CC side. The real existing paper money requires: ATM (millions of them!), terminals, delivery from/to banks/shops/offices/homes (delay), guards delivering money from ATM to/from banks (wages, fuel, equipment etc), additional security and staff in banks/shops/offices, printing and replacing damaged units from time to time, money safes and money counters in banks/offices/shops/homes, hard to measure cost of delay in transaction due to physical existence (e.g. consumer has to drive for money to ATM and return back).. etc. etc. Multiply by the all people on the world using physical money and I bet it will consume more energy than CC. Paper money must be recreated when it is too much damaged. It happens every couple months or years. Unlike coins, raw material can't be reused, so yours $0.05 per unit, is underestimated IMO.

Money, is it worth it?
In "good old times" (before "invention" of financial instruments) money was a tool to buy somebody time of life. e.g. anybody can sow the seed, harvest grain and bake bread. All by himself/herself. But it all takes time. There are easy tasks which anybody can perform with none or minimal schooling, and as a result they have low value per second, and there are hard tasks which have extremely high value per second of work. They require specialist knowledge and/or expensive equipment etc. Wages of working people, prices of products, expressed in local currency, are methods of weighting time of life of different people. The introduction of financial instruments, then movement to "worthless" *) paper (or equivalent) cash, then movement to virtual money in a computer memory/storage, broke the all rules.. *) "worth as much as we agree", which is/can be very volatile (Forex) and artificially intentionally modified.. If everybody would agree "we work as usual and nobody asks for money for anything" entire world would still work, a lot of good things would happen. Nobody would steal and kill for (not existing anymore) money. Crimes involving interception of somebody money would disappear. Narcotics and crimes related to them would disappear. The only narcotics dealers would be the one which are addicted by themselves. Some would say it would be "world of slaves".. But right now this world currently is "world of slaves of money"..

Money, is it worth it?
Sounds you never worked in IT corporation.. Some programmer told me that they (he and the team he worked for at a time) were making ~ 30 lines of code per month. Every change of line he made required meeting with senior software engineers, hours discussion, acceptance and sending to automated test drive taking hours or days, and manual test drive.. For somebody unaware, from external world, "lazy person" might be indistinguishable from somebody thinking how to do something efficiently, correctly, without introduction of new bugs and problems in the app which has millions of lines of code.. Techniques which are fast and cheap (for IT company) to implement, are usually slow and inefficient for end user of the application. Book writers, music composers, artists, programmers, often spend time on "nothing" (indistinguishable from nothing from layman's perspective), when in the reality they are doing work in their brain, thinking. Jobs which don't require thinking and creativity are easily replaceable by automats, robots, machines and computers. In physical work it is much easier to tell whether somebody is lazy or not by comparison of the results with other employees doing exactly the same task. In intellectual creative work it is much harder to compare employees results. ..wallpapers is low quality cheap finish.. Funny in the context of your previous statement "someone who spends all of thier time trying to find a way to do as little work as possible"..

Germination of Potatoes - and Its Effect on Cooking
Counter example: salted water has higher boiling point than pure water. Brine has ~ 109 C. When salt NaCl is added, the freezing point is lowered and the boiling point is raised.

Germination of Potatoes - and Its Effect on Cooking
@studiot Edible oils are not one uniform chemical compound. They are a mixture of saturated, monounsaturated and polyunsaturated fatty acids. What is the difference between e.g. refined olive oil and virgin olive oil? The percentage of fatty acids. Along with the difference in content, there are also differences in the physical properties of the entire mixture e.g. smoking point. A couple tables worth reading: https://en.m.wikipedia.org/wiki/Template:Smoke_point_of_cooking_oils and here table with percentage content they are made of, and how it influences properties (smoking point): https://en.m.wikipedia.org/wiki/Vegetable_oil#Composition_of_fats

Germination of Potatoes - and Its Effect on Cooking
If you want them to have always golden color, crisp skin with nice interior forget about shallow-frying.. Try this: cook potatoes with salt, vinegar and sugar at least 15 min. Dry carefully using paper and put them for max 6 mins in deep hot oil. Some use mixture of two oils to have higher temperature. Shallow-frying disallows them to evenly fry from all sides therefore you need to double time of frying. If you want to learn how much they took oil measure their mass before and after frying using both methods.

Money, is it worth it?
Reading you guys, I wonder whether you are living in a parallel Universe.. Meanwhile, in the real world: https://www.forbes.com/sites/niallmccarthy/2016/09/23/survey-69-of-americans-have-less-than-1000-in-savings-infographic/ "A new survey suggests that nearly 7 in 10 Americans have only $1,000 or less in their savings accounts. GoBanking asked 7,000 people around the country how much money they had set aside in savings accounts for the future, and found that 34 percent of them have absolutely nothing set aside." https://www.statista.com/chart/amp/20323/americans-lack-savings/ How can somebody being really happy knowing he or she is just two weeks out of work to bankruptcy (or homeless)? For most people, this is (or would be) an extremely stressful situation. (Hence the incidents of mass murder after dismissal from work of person "on the edge") Whether somebody earns $7k, $70k or $700k per year, does not matter. It does not tell about non-luxury obligatory spendings and debts. The stress of the person who owns a home bought on credit and knowing that its price is lower than the bank debt can have devastating consequences for mental health in times of economic crisis.

Money, is it worth it?
If you buy new CPU you need to buy new motherboard (because CPU socket has changed) with new RAM (because memory slots have changed) with new storage/disk/drive (because you don't want to lose old data or old one cannot be even attached) with new gfx card (because old one would be bottleneck or does not match PCI -> AGP -> PCI Express.. VGA -> DVI -> HDMI) etc. etc. In modern times manufacturers of devices decide for you instead.. forcing people to puchase their products. They could be giving CPU as free gift (like dressing gown from essay) and if somebody would like to have any use from it, would have to buy all the rest of equipment. It is widely used in modern computer games: base version given for free to download but if player wants to have any chance with a more advanced players must get paid additions (and perhaps at the end spend more money than he/she would in old times buying box version). Electronics break after a while of use. Elements are designed in such way to break right after warranty ends plus a small margin. You can't get into a shop or manufacturer and request a replacement for an element. It is no longer produced. Every year or every two years they design new models which have incompatible parts. Even the cheapest things are redesigned from scratch. Everything is done to disallow reparation and to force people to buy new product every couple of years.

Sign rule for multiplication
Let's inverse equation and use division: 6 / (-3) = -2 or 6 / (-2) = -3 Division is the inverse of multiplication. And vice versa. (With a little exception) In the simplest case: 1 / (-1) = -( 1 / 1 ) = -1 Left and right side of the equation must be equal.

The "Ice Bomb" thermal engine
(without reading comments above, so maybe somebody already pointed it out) A perfectly sealed object with fluid inside will behave differently than the same object with open air access, i.e. different temperatures and pressures will be required to change the state of matter. It is used to stupidify people by so called "miracle" e.g. https://www.google.com/search?q=naples+saint+blood+liquify which, from time to time, changes state from solid to liquid, and vice versa. Basically, water put it sealed bottle, won't freeze at 0 C and won't boil at 100 C. In the perfect gas equation v volume variable is constant so two other variables must change accordingly instead.

I really want to learn
Tool depends on task at hand which you must do. There is no such thing as "the best tool for everything". If you want to make website you just need web browser (which is built-in every modern system) and start your journey from reading and following tutorials on https://www.w3schools.com It is for IT beginners really. It is also good to have XAMPP https://www.apachefriends.org/ If you want to make Windows OS application, you will need Visual Studio Community or Express. https://visualstudio.microsoft.com/ C/C++ language reference https://en.cppreference.com/w/cpp/language If you want to make smartphone application for Android you will need Android Studio. https://developer.android.com/studio Java language reference https://docs.oracle.com/javase/specs/jls/se8/html/index.html All these tools are available for free to download and use. No. It is not good job. It is great job to learn. If you don't want to be "modern Neanderthal" not understanding anything around you..

Created a system for increasing integer storage
In the computer science, "integer"/"int" is primitive data type which is stored (typically) in 32 bits, regardless of what value it contains. It can be unsigned or signed. Unsigned 32 bit integer can store values between 0 to 2^32-1 = 4 294 967 295 (~4.3 (US/UK) billions). If not all bits are used, we can pack couple values into one primitive datatype. The simplest example of it is bit field: https://en.wikipedia.org/wiki/Bit_field e.g. if you have value ("value1") in range 0...16 777 215, which fits 100% in 24 bits.. you can merge it with yet another value ("value2") in range 0...255 which fits in 8 bits. data = ( value1 << 8 ) | value2; (which is equivalent to value1 * 256 + value2) To extract value1 from data we need to do: value1 = data >> 8; (which is equivalent to data/256) and to extract value2: value2 = data & 0xFF; (which is equivalent to data%256) In the more complex cases, there are needed left/right binary shift operators together with binary and (&) operators. Binary left-shift is equivalent of multiplication by 2^x. Binary right-shift is equivalent of division by 2^x (without remainder). And binary and (&) operator is equivalent of modulo. They are much faster for CPU than equivalent arithmetic operations. Knowing it, we can pack/unpack values which don't fit perfectly inside of bit/binary boundary. e.g. on the example of time: you have variables seconds and minutes, they are in range 00...59. Hours variable is in range 00...23 packed_time = ( ( hours * 60 ) + minutes * 60 ) + seconds you end up with value in range 0 ... 86399, which is stored in 17 bits (2^17 = 131072) Previously, you would have to have 3 bytes = 24 bits used not optimally for hour, minute and second variables. Remaining bits where always 0, just taking space. No, you did not. Rediscovered just the wheel. Widely known and used even by CPU engineers to save space in the CPU registers..

Physics of deep ocean
Really deep diving requires special procedures and special equipment i.e. decompression chamber otherwise diver will have decompression sickness which might even end up with death. You should read entire articles: https://en.m.wikipedia.org/wiki/Decompression_sickness https://en.m.wikipedia.org/wiki/Diving_chamber Hydrostatic pressure at sea level is 1 atm. Approximately 2 atm at depth 10m. Approximately 3 atm at depth 20m. and so on, so on, every 10m. Whether diver will survive getting out of submarine which sunk depends on depth at which he/she get out of it and availability of decompression chamber waiting for them..

Problems with Dell XP Standby modus
Did you try solutions from this thread? https://www.dell.com/community/XPS/FAQ-Modern-Standby/td-p/7514448 "Workaround for Modern Standby battery consumption and heat This option may be removed by Microsoft in newer operating system versions. * Highlight on the battery icon (bottom right) * Right click and click Power Options * On the left side navigation, click "Choose what the power buttons do" * On, "When I press the power button", change On battery and Plugged in to "Shut down" * Click Save changes * Go to Windows settings and select Power & sleep. There will be an option for Network connection: "When my PC is asleep and on battery power, disconnect from the network", change it to "Always" * Open Device Manager * Open the Network Adapters section * Right click on the Wireless adapter * Go to the Advanced Tab * Go to Properties and select Wake on Magic Packet and set the value to Disabled * Go back to Properties and select Wake on Pattern and set the value to Disabled * Click the Ok button and close the open windows Disable Modern Standby.

Pedophiles in the Soviet Union
What a poor introductory post.. None political wing, AFAIK, accepts pedophiles, child molesters, child abusers.... Acceptance to gays and lesbians, transsexuals, minorities, has nothing to do with acceptance of people raping, molesting or abusing people (i.e. doing things by force, or by trick, against second person free will..) (Typically) YouTube is a poor choice of source of the information about the world, unless a video is made by scientists e.g. Discovery Channel programs.

Speed of light (hijack from Time for a different view (hypothesis))
E=m0 c^2 is mass-energy equivalence! It has nothing to do with "speed of light"... https://en.wikipedia.org/wiki/Mass–energy_equivalence m0 - rest-mass (aka "invariant-mass") of object. When highly (relativistic) accelerated particle collides with other particle, there is created "shower of particles". https://en.wikipedia.org/wiki/Particle_shower Such "shower of new particles" can be seen by naked eye.. if you have Cloud Chamber, Bubble Chamber, etc. kind of early (and cheap) particle detectors.. @Prof Reza Sanaye The more (kinetic) energy has particle, the longer trace it leaves. The more kinetic energy has particle, the more energetic (and more massive) new particles it can create during collision. You don't need CERN to have highly energetic particle. They are coming from cosmic space. Passing through your apartment right now. You just don't know about them.
