Are you ? But +1 anyway. I repeat my observation that this is just a wind up. isaac, I've rumbled your game. So [game] - on The game being [Insert your favourite reptile] - on My favourite reptile is [Komodo drag] - on or perhaps [Pyth] -on Your move I believe.

Sure, hope Ghideon's help works out for you. He (or Sensei) should be able to log into your router remotely from the internet. I used to do this all the time to mine. But keep sensitive information to private messages.

That was a huge block of text entering into many areas which only have a tenuous connection or none at all. So many questions all at once, I can't tell which are important to you so here are a few thoughts. Phlogiston was not a 'force' theory. You are correct that it takes a finite time for a photon to interact with an atom or electron or for the generation of a photon from an atom or electron. This interaction time does not determine the energy of the interaction in any way. It is related to the energy by the Heisenberg uncertainty principle (HUP). The quantum of energy is determined by environmental factors which set the potential energy levels available to the system. If you can separate out and organise your questions better you will get some better answers.

Why can you not log on to the control page of your router ?

No. I do not know why I put a dot there, but to my untrained eye it looks neater. You need to consider just the first 3 paragraphs of my post together, and say what you disagree with. I do not have unlimited time to reply to everything. I asked for clarification, I can't agree or disagree as Idon't know what you are talking about So this is a wind up then. Thank you for confirming that and wasting my valuable time.

It's while since I needed to setup a router but there used to be a different set of IP addresses, outside of the normal range of local IP usage, for doing this since the computer acts as network controller (DNS server) and the router as slave when you first do this. Once you have done the proper setup, you switch roles on the devices. I also wondered if you had a smartphone with an (unknown or suspected) rogue app.

A couple of thoughts. You say you have nothing wifi equipped in your house. Are you quite sure? Even if you have 'disabled' it on the Chromebook, won't it will still be live inside ? Some modern televisions have internal wifi as well as Ethernet connections. Same with printers, scanners, doorbells and other auxiliary devices. Printers with wifi and ethernet are often a pain to get working on the right network. If you have such a printer is the chromebook trying to set itself to the printer's own local network and fighting itself if you want to use the router ? Do you have a 'firestick' or other interface between tv and home network ?

Thanks for the reply, but why do you say this ? Here are the front and back covers of a book from 1957. The front cover is about totally obsolete transistor circuitry. The back cover is an advert for an different book in the series about electrical powerline faults, powerline stuuf is still in date. Another really good example would be "Design of Reinforced Concrete to CP114" CP 114 was the design standard from the late 1940s to the late 1960s when it was replaced by CP110. There is a word of differerence between these standards. CP110 brought in "Limit State Analysis" Are you aware of Limit State Analysis in engineering design ? It is of vital importance in the modern world.

Thanks for the attempted help. Unfortunately your link is the same as the OP. Here is what I get, I don't deal with outside sites that do this.

I can't access the OP post because it "values my privacy" can we see what it says here please?

Surely it's momentum you want not velocity per se. I haven't computed exhaust momenta, have you calculated these for comparison ?

This might help How many valency electrons did chenbeier say Br- has ?

Just to expand on swansont's words. Can I gently suggest/offer a lesson in basic efficiency Physics? It take some energy once and once only to get a generator mass spinning. Once spinning all you loose (inefficiency) is the frictional loss in the bearings. The greater part of the input mechnaical energy is output as electrical energy. Of course there are also the inefficiencies of converting thermal energy to mechanical energy.

Two things are clear to me. 1) All other participents understood the gist of what you said the first time round so there was no need to repeat it. 2) You didn't listen to anything others said, since for instance you repeated your valence electron error (underlined), which is probably why you didn't respond to anyone.

Yes. That is what I want to discuss. Unfortunately my thread has been hijacked by Jogius with a torrent of meaningless nonsense, irrelevant jargon and personal abuse. Thank you for your answer. Have you read this paper ? It is only 3 pages long. However I cannot see a link between this first part of your opening post and thread title. and the second I was hopingyou might explain this in some detail ? In particular I am puzzled that you have introduced an expression involving 'Force' and 'Time' when the reference does not mention force or time anywhere. I am further puzzled by your notation. What exactly do you mean by [math]F\left( {\int {V.dT} } \right)[/math] ? Are you intending an inner or dot product ? How does this work with a vector and a scalar ? What physical quantity do you think it represents ? The only real agreement between Einstein and yourself seems to be that in both the 1905 papers Einstein was working with 3 dimensional vectors as you appear to be. Of course, in 1905, four-vectors had yet to be introduced in Physics.

The one thing that doing your homework for you is not is kind. I don't see any attempt described here.

Yes you may have done, but did you give a proper reference ? Are you referring to the 1905 paper Ist Die Tragheit eines Korpers von seinem Energehalt abhangig ? : Annalen der Physik 17, 1905 (Translated means - Does the inertia of a body depend on its energy content ?) Which is a short paper that ends with the conclusion Or are you referring to section 10 of the 1905 paper on Special Relativity - The electrodynamics paper ? Which section is entitled (translated) Dynamics of the slowly accelerated electron.

Actually it's alkali that attacks glass, not acid and lead salts of most acids are not very soluble at the best of times. And 15 minutes. But hopefully like burning one's fingers once, one hopes to learn not to take chances again. Also the stuff will accumulate more in the dregs, and I doubt the child sipped those, but the good professor from Carolina probably analysed the whole contents of the glass, dregs and all.

Thanks for the answer. The OP doesn't appear to have been back and clearly copy/pasted words from somewhere (the background gives it away). The question looks to me like one of those stupid projects set by arts graduate teachers to 12 year olds, who have not yet had the benefit of much Science teaching. If this is the case then it would be good if we could offer some proper analysis and guidance, for instance pointing out that the elctron is 1800 times lighter than the proton/neutron and there are an average of perhaps 50 of these in a typical metal so most of the input themal energy will go into increasing the vibration rate of the nuclei to raise their temperatures.

A good way to measure it. But remember that would be after the wine has stood in the glass for a couple of hours. As chenbier noted how many sips per teaspoon ? And how long was the wine in the glass ?

Impossible to provide a number. But you should take heart because it can take at least an hour, probably several before appreciable amounts of lead appear in the drink and this is per litre ot per glass. So divide you figure by the number of glasses per litre, divide it again by the number of sips per glass and divide it again by a factor of 2 or 3 depending how long grandma held the glass before little one tried her couple of sips. So I doubt any harm was done in this case but just make sure lead crystal glasses are not used again for anybody. North Carolina State University carried out a study of how much get into a glass and how long it takes. Angela M. Fraser, Ph.D., Associate Professor/Food Safety Specialist, and Carolyn J. Lackey, Ph.D., R.D., L.D.N., Professor/Food and Nutrition Specialist, North Carolina State University (2004)

Is this a school project ? Well spotted. +1 25% * 2 = 50% Why stop there ?

I will answer this for you as many others have this false impression that QM only applies to the very small. This arises because the energy (transitions) involved are very small and therefore individually only affect very small particles. So an individual quantum energy effect (transition) can only affect a minute part of a (large) macroscopic object. However when lots of these small transitions all work together they can affect large objects. The effects include our everyday Physics so this if I push a large block of metal, it is all the small quantum effects working together that hold the block together so that it can move as a solid body under Newton's Laws. No esoteric Laws and effects are required. The whole of our macroscopic world works as it does because QM is the way it is. Hope this helps others as well. Season's Greetings to all.

Thank you for a practical demonstration that many youtube videos are unreliable, so as to be unusable as a source of evidence. Which is why they are frowned on in ScienceForums. I will be able to point to this thread in future as good reason for upholding that policy.

How long is a piece of string ? You haven't said what you have been taught so far or what you are objecting to. There are no short cuts and there is great danger in trying to take them. Both the differential calculus (which joigus mentioned) and the integral calculus are of vital importance in Physics, Chemistry and Engineering and increasingly so in the softer sciences like Biology and Economics. The important thing for someone wanting to benefit from the calculus is to understand what is going on. Tables of results and algebraic manipulations are readily available but you can't manage without being able to follow so many derivations. For examplea The potential energy of an electric charge in an electric field is evaluated by performing an integration of the work done as we move the charge from infinity to its position in the electric field. Both the First and Second Laws of Thermodynamics require knowledge and understanding of differential and sometimes integral calculus to be able to use them. Even the simple equations of kinematics taught in secondary school require this if derivation or more advanced application is needed.
