When I bought a new digital watt-meter *) approximately ~7 years ago, and started checking every device one by one in the apartment, I identified several such devices in my home.. e.g., the computer speakers and cable TV HDMI recorder were consuming ~90-100% of the regular power usage, when they were supposed to be turned off with the button and/or in stand-by mode.. *) Best purchase for everybody who wants to reduce energy usage and worried about global warming.. just 10 euros, its cost paid back within a month of use after checking the all home devices.. You plug it in between device, and socket, and leave it overnight. One device, one 24h day of checking. To see energy consumption in that period. When you use device, and when you don't. Then open spreadsheet in Open Office or Excel and enter data. Extrapolate to entire year and sum the all devices together, calculate percentage of usage -> you see how much you can gain by having it unplugged/disconnected by splitter which have buttons to shut down the all sockets. I have such electric splitter which has one the main button, and buttons for each socket independently. Search net for "Electrical sockets controlled by remote control". https://www.google.com/search?q=Electrical+sockets+controlled+by+remote+control Yet another "best buy" for somebody who wants to be ecological.. (but check it by watt-matter also it has to be in stand-by mode to support remote access)

https://worldpopulationreview.com/country-rankings/energy-consumption-by-country Click interactive map to see country details. Per-capita data. More valuable than absolute value. In US, as some says, "sky is the limit".. Significantly higher average energy usage per-capita than elsewhere.. ..nowadays I have 550 Watts computer power supply.. CRT's were certainly consuming a lot of energy per device but nowadays 50-60" LED consumes 80-100 Watts. Check your TV device power supply. People in Western countries have a couple devices. One for each family member. Everybody wants to watch something else. In US large chunk of energy usage is used for cooling interiors. Great usage of roof solar panels, not requiring transformation DC ->AC and storage in batteries..

Too ambiguous. "Very old" for most modern people are devices of 4 years or more. Give the manufacturer and model name, operating system version, etc. etc.

You can have Internet configured statically or dynamically (DHCP). https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol If it is static, you must enter the IP addresses manually. If it is dynamic, when establishing a connection, the computer asks the DHCP server (usually a router) for the local computer's IP address, gateway, IP mask, DNS servers, etc. A dynamically configured Internet is less secure than a static one. If a hacker intercepts a router and changes the configuration of DNS servers in it, he/she will immediately find out what sites we visit. This is especially dangerous in free hot-spots of unknown origin (rented apartments, hotels, hostels, restaurants, shopping malls, streets, etc.). To find out about DNS servers on a Windows machine, the user can open a terminal ("cmd" in Start), and type "ipconfig /all". This can also be done in the UI. On Linux, https://www.google.com/search?q=how+to+check+dns+linux https://askubuntu.com/questions/191563/how-to-view-the-dns-address-assigned-by-dhcp If the DNS servers provided by your ISP (via DHCP) do not work, try using Google DNS servers: 8.8.8.8 and 8.8.4.4 https://developers.google.com/speed/public-dns/docs/using Google DNS servers are usually slower than ISP DNS servers, but their IP addresses are easy to remember, so just in case of local DNS problems (or hackers breaking in and intercepting your ISP DNS servers), it's good to know how to change your settings to static and use Google DNS servers instead. The "nslookup" command in the terminal will tell you which DNS server was used to query the DNS entry. Either on Windows and on Linux. e.g. nslookup google.com ; it will use the default DNS configuration (perhaps DHCP, perhaps provided by the ISP) nslookup google.com 8.8.8.8. ; it will use Google DNS servers instead of the default DNS. so if you think hackers have hijacked your DNS server, you can verify this by comparing the results of these two commands. (but some DNS records may be location dependent https://www.google.com/search?q=DNS+records+location+dependent ) Too ambiguous..

Some have said that "the man with one eye is king in the land of the blind".. ..or nobody wanted such an unpleasant position as PM in such a time like Brexit..

Being "massless" in physics mean "having no rest-mass" (aka "invariant mass"). Did you see photon at rest? Particles, molecules or objects, with mass ("rest mass", "invariant mass"), can be accelerated and decelerated i.e. their frame of reference can be changed.

I like your style. Intelligent and gentle replies. When you read dimreepr's posts, you badly need the Universal Translator from Star Trek...

The modern alternative, in a digital society, to the medieval "sealing wax" is the digital signature: https://en.wikipedia.org/wiki/Digital_signature Unfortunately barely used by ordinary people. Therefore hackers can pretend to be friends and family while conversation by e-mail and send malicious content or links to malicious websites. A common route of infection for politicians and businessmen (mostly as experienced in computer science as ordinary people).

Dried animal poo is widely used instead of wood in many regions of the world where wood is rare. Even nowadays.

So far it sounds like A.H... Still sounds like A.H... "Strong united nation" against some true or imagined enemies/political opponents.. Some parts are mutually exclusive with other parts of your statement.. How to unite people against the industries they work for e.g. miners, oil & gas workers etc. ? They want to continue living the way they used to, while crying how it happened they and family got cancers and other illnesses caused by what they do for living entire life, sometimes generation by generation..

In Android 5 and below, you need to install a 3rd party app. Pick up one from the Google Play Store. In Android 6 and 7 you can enable "Now On Tap". If you don't want to, or in your country it is not available, install the 3rd party app like above. In Android 8 and later, QR code reader is built-in a camera app, but you might have to enable it in Settings. Different device manufacturers have different camera apps, so search the web for "how to enable qr codes " plus your device model name and OS version.

...apparently "lost in time"..

...reminds me Volkswagen...

Really? Where? 1) "Parallel Universe".. 2) Or: ps. Haven't you seen the TV series where the nazis win WWII and the US is divided between Japan and Nazi Germany? Tom Swanson would be leader of guerrillas.. ? (I will see ("observe") this Parallel Universe and I'll tell you what you did there...)

Majority of ordinary people in the world, including politicians, government officials, and even including members of this forum (looking at the posts that pop up every time there is a discussion about "rich people" and taxing them) have been fooled by the "Billionaires List" in various newspapers/magazines.. These lists are compiled based on the stock prices of companies that "rich people" own, control or have a stake in. Very confusing to properly assess their wealth. For example: Elon Musk is 2nd on the Forbes list.. right? Wrong, incorrect, and misleading information! https://www.google.com/search?q=tesla+debts "Tesla had started 2017 with $3.4 billion in cash but had $10.2 billion in debt. This was a negative cash position of $6.8 billion." https://www.google.com/search?q=tesla+debts+2020 "According to the Tesla’s most recent financial statement as reported on July 28, 2020, total debt is at $14.10 billion, with $10.42 billion in long-term debt and $3.68 billion in current debt. Adjusting for $8.62 billion in cash-equivalents, the company has a net debt of $5.48 billion." https://finance.yahoo.com/news/teslas-debt-overview-120614517.html Share prices are out of touch with reality, artificially inflated by demand, by corporate marketing, by CEO personality/celebrity etc. Share prices reflect not the real (current) valuation of the company, but the futuristic, possibly unattainable future goals of the company. Any attempt to sell a majority (or enough significant amount) of shares could lead to a price collapse if no one is found willing to buy them back. Stock is often used by financial institutions as collateral for loans. A drop in the price of the stock below threshold in details of loan, forces the financial institution to request another surety and/or sell the stock, causing the price to drop even more.

If we're on taxes and taxing billionaires, there's the question of which country with which people in government, and whether they're willing to spend the money they raise more optimally than a billionaire can do himself/herself.. If a billionaire spends money on luxury items, the money barely reaches the bottom of the economic food chain.. If he/she invests money (in non-financial industries), new jobs, new industries, new opportunities are created.. This is a mathematical equation with many variables that change over time and space.... rather than an ethical one.... Bees, ants, termites etc. social animals work for the goodness, prosperity, happiness of the entire group and family to which they belong without any money.. Can you create more and efficiently with your neighbours and family than if you paid them or they paid you? Money has degenerated human.. degradated human.. unequalled human.. partitioned humans.. People started doing many evil/inappropriate things they wouldn't do if money wouldn't exist.

You can print a graph by typing the equation into Wolfram Alpha, and you will see (at least graphically) if it (or any equation) is near zero (or in any other range): https://www.wolframalpha.com/input/?i=(+x^4%2F(85^2+%2B+x)) for equation "( x^4/(85^2 + x))"

Yes. Paid studies create many pathologies, such as poor students taking out loans and/or having a second parallel job to even attend college. A full-time job reduces the time by 8hrs a day that they can devote to their studies, increasing the chance of failure. If a student fails, the loan does not disappear. An exceptionally bad start in life with long-term consequences. It would be interesting to see the statistics of failed studies per country, the cost of those studies, and the percentage of students who took out loans for them and how quickly they paid them back. And similar data. From your personal experience: what was the initial number of students in your major and how many of them "made it" to the end and graduated? Free studies can also create patologies. e.g. carelessly choosing a course of study for oneself and easily dropping out at no cost at any time without serious consequences, which, with limited seats in the class, means that someone more suitable was rejected and had no chance to participate. There are people who do not value what they got for free and/or take it for granted. The number of seats in a class each year is limited. This is a natural barrier to too many students in one subject of study. The best ones pass through. They have a chance to successfully complete.

Try instead: NSolve[( x^4/(85^2 + x)) == 1,x]

In different versions of Android you change it slightly differently. In my I simply type "font" (the local language equivalent). Font sizes are stored in sp units (scalable pixels). Other elements dimensions and borders are in dp units (density-independent pixels). https://developer.android.com/training/multiscreen/screendensities Adjust it to Small. Restart device. Adjust back to Large. Maybe what is displayed in UI was no stored in config files. It can happen if application's activity is delaying saving settings to onPause/onStop/onDestroy, but sometimes Android OS don't execute these methods (especially in out of memory situations, or when app is terminated due to crash, i.e. when app is unexpectedly shutdown)

Scientists in laboratories can create a single photon at a time and detect a single photon at a time. Scientists in laboratories can eject and accelerate a single electron at a time and detect a single electron at a time. Scientists in laboratories can eject and accelerate a single quantum particle at a time and detect a single quantum particle at a time. Want to see them? Build Cloud Chamber: Here we have a single quantum particle, of various types (e.g. electron, proton, alpha, muon, pion, kaon), accelerated to near the speed of light, colliding and decelerating with atoms in the medium... or a simulation of it, if you are a "brain in a vat". What does it mean to "see something"? The scientific version: atoms in your retina are excited by photons and create electrical impulses. https://en.wikipedia.org/wiki/Retina "In the photoreceptors, exposure to light hyperpolarizes the membrane in a series of graded shifts. The outer cell segment contains a photopigment. Inside the cell the normal levels of cyclic guanosine monophosphate (cGMP) keep the Na+ channel open, and thus in the resting state the cell is depolarised. The photon causes the retinal bound to the receptor protein to isomerise to trans-retinal. This causes the receptor to activate multiple G-proteins. This in turn causes the Ga-subunit of the protein to activate a phosphodiesterase (PDE6), which degrades cGMP, resulting in the closing of Na+ cyclic nucleotide-gated ion channels (CNGs). Thus the cell is hyperpolarised. The amount of neurotransmitter released is reduced in bright light and increases as light levels fall. The actual photopigment is bleached away in bright light and only replaced as a chemical process, so in a transition from bright light to darkness the eye can take up to thirty minutes to reach full sensitivity." Do you see electric field, magnetic field, gravitational field? No. You see just EFFECTS of these fields on surrounding environment i.e. how other quantum or macroscopic objects change path and react to them. If you see something, does that mean it exists? There are people who claim to see something or someone, hallucinating, after or without abusing psychedelics or drugs. In the middle of this photograph, we see an arrow < that marks two particles coming from nowhere. How is this possible? An electric neutral quantum particle leaves no trace, but its decay produced two new, extremely highly accelerated charged particles. Again, we only see the effect and do not see the source. Therefore, the gap is filled by the theory (undetectable neutral quantum particle).

I think physicists fall into two main groups: theoretical and experimental. It's easy to be a theoretical scientist because it costs nothing, all you need is a piece of paper or a blackboard, but rarely is a theoretical scientist successful, i.e. most theories end up in the trashcan. This is in contrast to experimental scientists. They work in laboratories (CERN, particle accelerators), performing experiments and find discoveries. Einstein did not get the Nobel Prize for his theoretical work. He got it for his explanation and formula for the photoelectric effect. You may have a mistaken impression of scientists on the science websites, because online scientists mostly respond to posts from laymen coming up with new revolutionary theories. They have some "most liked" topics: black holes, dark matter, dark energy, and GUT. All these are topics for which there are no scientific answers as it is impossible or nearly impossible (for now or ever) to study these phenomena experimentally. If you are looking at the Sun, a star or a distant galaxy, your eye, a scientist's telescope, has just absorbed photons. Billions+ of photons with properties: frequency and polarization. The more photons detected ("measured"), the better the image quality. How can you know... to be absolutely sure... the Sun, stars, distant galaxies really exist and are what you think they are? No one has flown there. No one has touched them. If they really exist and are what physicists think they are, no one will ever get to them because they will burn up any device. Therefore in physics we have a division between direct measurements and indirect measurements. https://www.google.com/search?q=indirect+measurement+physics
