#1 - The bigger outside coil should be pushing more refrigerant to the smaller indoor unit than it can handle, which makes me wonder if your brother has this right. The inside unit should be bigger, but if it's smaller by a ton there would be some problems. Some of these units give a range (it can push 2-3 tons), so have him double check the size. #2 - Carrier systems pushed R410A through the EPA, and it's caused compatibility issues. I'm told R410A operates under much higher pressure than R22, but as long as the system is tightly sealed you should be OK.

Then people would be allowed to make up their own mind, you know "free", to vote in a democracy that actually represents the value of your vote; rather than an imaginary enemy...

You lost my interest long before that...

Please contact your doctor or family members and let them know about these thoughts you are having. Take care and have a good day.

Thanks for your opinion of a definition; fortunately the well informed are armed with a dictionary and so can escape a pointless argument... 😉

I would use a handheld XRF Spectrometer. It gives you an instant qualitative and quantitative results of the alloy. Quite impressive instruments; I used one for a while a few years back.

I think joigus has your answer but I would like to elaborate a bit further. It's very often the external pressure that counts, especially in chemcial reactions since the reactants in the open test tube are pushing against the armousphere, which is sensible at constant pressure. So this will be PV work done by the system on the surroundings. As joigus notes the internal pressure of the system is not measurable. Thermodynamics (first law) is about the energies and masses crossing the system boundary and you will often find the calculation easier on one side or the other of this boundary. Finally this is for irreversible work. A reversible change would be carried out so slowly that the internal pressure always has time to equilibrate at each infinitesimal expansion or contraction.

IR radiation is of the right order of frequency to set up vibration in molecules which have a dipole (partial charge separation), giving up its energy to the molecule in the process. So this is what makes a molecule absorb in the IR. What you are seeing is absorption due to different modes of vibration of the molecule. CO2 can stretch or it can bend. I rather think the left hand band is the stretch and the right hand one is the bend. So it's not several different species. It's all CO2. In general, the IR spectrum of a given molecule has a number of absorption regions, not just one.

Just like differences between types of conervatives and liberals, there is a huge difference between 'soft' and compassionate. The idea is not one extreme ideology, or the other opposite. It is a combination of the two which yield the most benefit for all people. Democracy does that much much better than authoritanianism/dictatorship.

And yet... you just replied to this post, acknowledging both it and the former, however responded to the legitimate queries of neither. So the cycle continues... Evade. Ignore. Rant. Lather. Rinse. Repeat.

And the very people he is defending are Russians and Chinese, both Communist, which is, by definition, left. Authoritarian governments ( dictatorships ) are authoritarian no matter their political leaning; extreme right, or extreme left.

The Left wants you to have universal healthcare coverage, which isn't tied to your employer and would cost a fraction of what most folks pay now. They want you to have bodily autonomy and be the ultimate authority for what is done to you physically. They would rather support you financially so you don't turn to crime than put you in prison for being poor and desperate. They want people to have equal rights under the law. They want to be governed by principles, not authoritarian commanders pretending to lead. They want everybody who's eligible to have access to voting, and they want them to exercise that right. The way I see it, you either have to think those things can't happen, or you don't want them to happen. Which is it, and why?

One thing I’ve noticed about folks with similar stances is that they never seem to be able to articulate what their specific issues are. It’s always some vague complaint, often citing some caricature of the group they are railing against. Manufactured outrage, based on propaganda rather than fact. I note that you aren’t denying that you’re failing to follow the rules, only that you see it as a burden and blaming others for it. Am I the chief or the sidekick?

Do you need a tissue to wipe away all those crocodile tears? I bet all of those people brutalized and murdered and tortured under autocrats and their sycophants would disagree, but thanks for showing your true colors and coming out forcefully in support of dictatorship over freedom and democracy of the people. It’s refreshing to see someone so oblivious to history. Oops… not refreshing. Meant repugnant.

That'( i)s how you (would) do it. E.g. Just so you do NOT have to bother. But why should I (try to) believe you. You have given me NO proof, with your inability NOT to bother (attitude). Are all scientists so lazy (like Minkowski hinted about Physicists)? (Surely NOT!) Why should (some of the kinetic) energy leave that system? (& I DON'T accept warm, acoustic, excuses either.) (I'd like to see (simple) tangible measurements.) Oh! Abracadabra (then). (It's a mystery!) That sounds like a boring disinterest in science e.g. trying to know. A half hearted attempt to throw a few things together. You either: know; or (else) you DON'T, & you obviously DON'T, because you give me useless excuses. Sorry, other people can try to be more thorough. You DON'T even give the effort. If you (were to) say: those answers can NOT be found; then there must be a reason why. (Oh we are too feeble, (at) attempting, (to) zero_speed, =zero results. It's more difficult that c.) Disinterest is NO excuse. You also avoid commenting (up)on the (=my) initial_kinetic_energy KEi (perhaps because you habitually evade it by subtracting it away). My syntax includes KEi. (What is your syntax, if mine is NOT an extended (syntax)?) All 3 (named KEs) KEf=KEi+KEd are "kinetic_energies" ((meaning) NOT your "the"(what? _unknown), NOT mentioned f form) syntax). You can clearly see that (they are kinetic_energies) in my syntax "KE" with a subscript. There is NO difference: meaning a KE is a KE, whatever its subscript is. The KEd can (equally) accelerate a(ny) mass from zero (speed) to a (new) final_speed vf, which would finally have its own KEf(new)=KEd equal to that kinetic_energy_difference KEd. I DON'T see why you try to sell a KEd distinction (away) from any other KEsubscripted just because you do NOT know what (else) KEd is (or could be). E.g. Even though you only want KEf to be "the" (only) kind of KE (possible). It is absurd to say: KEd is NOT a kinetic_energy simply because it is NOT "the" final_KE KEf=m*(vf2-0)/2 which uses the mass m multiplied by half the final_speed squared vf2 but "subtracted by zero(_squared)"! The initial_kinetic_energy KEi=m*(vi2-0)/2 is also a kinetic_energy (just like KEf is) because its half the initial_speed squared vi2 but is also "subtracted by zero(_squared)"! The universal KE_difference formula KEd=m*(vf2-vi2)/2 is the most universal KE "definition"! There you can (=may) use any reference(_frame) speed vref=vi (below c, that) you want to be your reference speed (e.g. at rest, when identical to the initial_speed vi). If I have 7 oranges (analogy KEf) & subtract 4 (oranges, analogy KEi), then I would expect out, 3 (oranges, analogy KEd) like any reasonable thinking person. NOT grapefruits or "lemons"! (or other hogwash). That's only common sense, which seems to be missing here (in (what some people call) science). You DON'T (even) have a clue where the energy has gone, you DON'T know what it is (e.g. called, other than "difference") & yet want to be called scientists. (& you want me to believe you?) Modern physics is like modern art, anything goes, even junk. All that matters is who (e.g. what ego) has the say. I suspect you mean, the initial_speed terms (e.g. KEi) are subtracted anyway; (&) so why bother. ? Taken from a different perspective, of: if the 2 masses are on Earth & the Earth is rotating let'( u)s say vi=~1 [km/s] eastwards ((just) to keep things simple, at where they are on the Earth's surface); then they are still moving ~1 [km/s] although they appear to you as at rest. (& that KEd did NOT leave the system.) What seems (as) "at rest" is an optical delusion (of) for both: observer; & an object, having the same (=identical) speed. (E.g. Even though they are separated by a distance d.) In reality (e.g. the universe), (we know) everything is moving. Meaning NOTHING is (really) static (=at rest, with zero speed). (Everything has a speed difference wrt some other (moving) object (reference, frame).) Your "choice" of reference(_frame) (e.g. of same speed as the observed object) (help) determines whether you want to be: deceived ((in)to think(ing): ) an object is at rest (when it has the same speed as the reference_frame); or NOT! **(Sorry! (Yes) "I") Modified. (Or do you mean your quote is dishonest? Which I (rather) doubt, in preference for the former.) How else should I add (extra) comments of mine into your text? I bracketed it, to distinguish it from your original text. Dishonesty was NOT intended; only clearness of the discussion (was intended), (before getting lost again in(to) confusion between syntaxes). Should I use different brackets?

LOL!!! Well I suppose you would prefer or more mundane explanation, but when rockets are fired into the air and then UFOs show up, what would be your first guess? Yeah! There is actually more evidence of aliens and spaceships then there is of parallel universes. I still don't really understand the Many World Interpretation argument. I think it's trolling, like the next level of flat earth nonsense. But seriously, there is more evidence of UFO crafts being caught on radar, infrared, visual, pilot eyes on recognition, etc. No evidence to support the premise that it's the Russians.

The title of the thread is: Why can't the philosophy of science be: Do what the aliens do. I think the answer is that, you don't know how. So let's do examples. Example 1: Strange phenomena is occurring at location X. Back story dates back to native Americans. Misguided Physics Community: ignore it. Call it woo. Call everyone involved delusional. Buy Sean Carroll's book: how to make money swindling physicists. Aliens: Investigate strange phenomena. Perform experiments. Gather data. Tell everyone in the community who will listen about what you saw! Example 2: Aliens try to make peaceful contact with humans by making their presense known through culture and a little bit of UFO movement. Misguided Physics Community: Ignore it. Look at anyone who talks about it with great suspicion. Blame the Christians. Aliens: Pick up the phone. Try to act normal. Example 3: Communicate in non threatening ways like, promote a meditation movement. Promote a religion that believes in aliens. Preach peace and tolerance. Misguided Physics Community: Assumes the worst: tentacles with giant mouths they scream "we're gonna eat you!!!". Aliens: Assumes their intentions based on how friendly, persistent, low stress meditated,... this must mean that we should call upon them for a meeting. Example 4: Start to think about what the aliens want. Misguided Physics Community: Assume that the woo is out to get us!!! Run around screaming "it doesn't exist!!!". Try to jump into glowing green light and act like you're Rick and Morty. Do anything completely un-called for; like you're panicking. Aliens: They must be here to give us their technology and love humanity. Treat all life with love,care,concern, and someday it will treat you with love, care and concern. Example 5: Actual message from the aliens: The Age of Aquarius is upon you. Like a mighty dog from another planet, the Aquarius age bites you on the butt, like a friendly happy alien dog that wants to receieve what we put out. If you want love, you gotta put out love. Even to the other planets. Because what fun is life if you can't fly to Earth, abduct a few for "scientific" sex experiments. ... is this what aliens really think? Misguided Physics Community: AHHH! Kill the woo! Kill the woo! Aliens: Not sure you wanna make friends with aliens who abduct your women... and men... for "scientific" research. Ever see a grey alien with makeup? As you'd imagine, it's pretty weird! Aliens say: ALL HAIL THE HUMAN PHYSICS COMMUNITY!!! YOU MAKE OUR CAMMOUFLAGE SECURITY PROGRAM VERY PROFITABLE. WE CALL IT THE: DON'T GET THE HUMAN'S ATTENTION, Security system. It's designed to keep out the stupid. It works so well, we should give the Human Physicis community a bonus check. We aliens cannot understand how you physics community humans can be so... um.... like you should roll everything that's been published back to General Relativity, particle physics... the aliens are now telling me that superstrings and loop quantum gravity <thumbs down> . But anything that looks like warp drives, pay attention to it. Anything that you pay attention should be worth paying attention to. That does not mean you should that American Values are up for targeting. We like the United States. It has given many people their rights. Soldiers have died to make you safe. Think of second amendment freedoms as a sign that good things are worth defending. Aliens want the human physics community to know that if you are forced to be "atheists", that you should stand together as a force to be reckoned with. Whether you are on the side of religion or you are off the map, is your choice. I'm just saying that the aliens think that humans who are atheists should should keep their opnion to themselves. If we wanted your opinion, we wouldn't bother giving you one. Did you know that the aliens know the answer to your problems. We just can't tell you. *wink* you're supposed to figure it out on your own. *wink* Like SMILE! HI! Do you get it? Wink! But you wouldn't believe us if we just told you that we want to see humans happy, and not so missile oriented. Seriously, and if you could just be happy, with each other, like a good neighbor, and no threaten us with your pointy megakill pointy things.

Be advised that we will slip in little mis-directs in our jokes. Watch that the joke might flatter you when you were expecting an insult. Are you still angry about last night? I mean, about the baloney? Does anyone think that my version of the truth is a little pointy? I mean, I try to make jokes. But they don't seem to get them.

You lost my interest when the gaslighting started. Where is the funny part. It doesn't even look like you tried to insert anything funny. Do you act stupid to entertain yourself? You have hurt feelings all over where your humor is supposed to be. May you find a joke so funny, that it beaks off all of the hurt feelings. This doesn't look anything like reliable evidence. This looks like a character assassination against someone who you don't like or agree with. It's all your opinion and not worth two pounds of bologna.
