Physics breaking, twice observed, says article
PB666 replied to PB666's topic in Science & Spaceflight
It felt like that with that article. Here's something even more disturbingly bad. https://www.youtube.com/watch?v=liXOb5JXg6w I have to say I face palmed when I saw their visual rendition of inflation. (this one didn't even deserve its own thread, but similarly psychotic) -
http://www.scientificamerican.com/article/2-accelerators-find-particles-that-may-break-known-laws-of-physics1/?WT.mc_id=SA_SPC_20150910 Im not putting out their conclusion, just linking the article. The articles states that two collidors are observing an excess of leptons over other expected types of particle.

Don't confuse the visible universe with the universe, also don't confuse the appearance of matter with matter, what appears to be matter at great distance could be antimatter, we have no way of distinguishing the two. It matter and antimatter boundaries were far enough away the comoving space-time could keep them separated forever, chance anti-matter matter encounters my show up as gamma rays, but at such low density and spread over time that we might see a filament and otherwise nothing. The answer to the question is that no-one knows for certain where the anti-matter is, the only thing we know with certainty is that it is not nearby, in our local galactic cluster or super-cluster. I personally think it is a boring question, since ultimately we cannot use the antimatter no matter where it is, we don't have the means to travel there.

KSP in Win 10? Does it work?
PB666 replied to TronX33's topic in KSP1 Technical Support (PC, unmodded installs)
Alright fine how do I install it, I have windows 7 on my system now, I am going to give this one to my wife, my new system needs an OS, The dual boot 10, ubuntu didn't work apparently it does not recognize a win10 partition, and it looks like my old SSD is starting to get glitchy. How can I pick myself up a OEM version of 7?????????????? Am I going to be able to live with linux, aarg, someone convince me that life without windows is possible. lol. Oh bill, where are you when I need you, off selling drug coolers in Africa, what happened to the programmers/diy paradise you created, its falling into the device black hole. Ever since that melinda woman came along things haven't been the same. lol. look linux is trying to steal your old girlfriend, the clone, shes straying. -
Prions are not proteins, they are a cleavage product of proteins. Autoclaving on metal can theoretically actually create prions, but chemical sterilization with dimethylforamide or acetonitrile in an organic salt like ammonium acetate at sufficiently ionic stregth can remove protiens or polypeptides. A prion is a bodily protein catabolite that for whatever reason has not undergone normal breakdown or clearance, and its presence provides a positive feedback loop resulting in increaingly more build-up. The brain unlike most other tissues does not undergo cellular turnover, and many proteins are expected to survive a lifetime once produced. It is not surprising that prions or alzheimers diseaes exist given the mean lifetime increase from the stone age to present, particulaly if we consider selective pressures during the medieval period and their equivilants in Asia, and all the nasty chemicals that firing and industry put on our food. Not interested in this topic, too much like work.

The skipper is my kauch engine before mainsail, and is my second stage engine after. i generally keep the skippers initial TWR at 1g, same as mainsail, i use booster with fuelinned aerotanks on top to get the mainsails vertical momentum, then i can toss the boosters and allow thrust and dargvto balance until about 250 m/s and generally im above 20k when i fire skipper, can often find some fairings or a nose cone to toss of and its pretty much orbit with leftover for transfer out. Even if i have to go size3, i am still going to skipper my second stage, the only tine i wont do this is if i have enough dV to reach around 90% of orbit dV required, and then i will go with a poodle. The main usage was for refueling the satellite celestial science lander. As for side mounted, yeah, not often, but sometimes you have a launch system with a payload and you just dont want to go one size up on the launch, generally 4 of these, will do. The little side mounted sat engines i use on my command chair lander.

They used to say the same thing about autism and gluten, autism and vaccines, but it wasn't true. What is true, the last thing parents want to know, is that there is a clear link between autism, schizophenia and the age of the male parent at conception, and we know why also. At puberty sperm cells under replication, so that by the time a man is in his fifties those cells have tried to replicate through cosmic ray damage, chemical damage, polymerase errors, etc and the Nascent SNP rate in males is about 4 times that of females during that period of the mans life. This is why comparing most of the chimp y chromosome to human is almost impossible, it has a genome relative divergence time of 60000000 years. As for climate change, woe is the nation that ignores this, and its now not just climate change, the oceans are changing and fast, the CO2 from the 50s and 60s that underwent solvation during arctic winters of past decades is now starting to well up in the temperate zones and shellfish encrustation are starting to faulter. CaOH is the fix, but that just adds more carbon. The oceans will not absorb CO2 like the past, we had a reprieve in the past but that is about to change. You may not chose to change your habits, it matters little; you will need to change you coastal defense, your water plan, you flood plans, your insurance coverage, your military and humanitarian aid, your birth control strategies in some countries, care for the elderly and young, food storage strategies, agriculture strategies etc. Climate change is not about global warming, though this is happening, its about disequilibrium. The problem in our thinking is that we were at the end of a climate optimum; the little ice age was a prelude to the big one. The industrial age stopped this and there was a balance for a time, but now the we have overwhelmed the original problem and the flip fron neutral to change was quiet unexpected even by scientist because for 150 years the system as a whole appeared immune to our activites. Sso human societies now need some time to assess and change. This is not about illiteracy or science, its about human beings realizing that the earth does not belong to them, but they belong to the earth. We can flip this, but we need to grow more socially to mesh ourselves into the environment better and plan better on a global scale. the problem for some industries is bad, In 20 years or so from now i wouldn't want to be in the airline industry, they better have alternatives. -
So i am going to make one general response because it is clear based upon what you have selected that you prefer some types of builds but not others, that if you want to master the game you need to start dreaming about other types of constructions. So for example. The micronode. In my prototypical space telescope, analogous to the Webb telescope, this part was essential, it was also essential in building the prototype space factory. To use the micronode you have to master the turn funtions in the vab, the is only on valid attach node and 5 valid attach 2 nodes, so you have to turn the attach to node to some node starter, such as radial starter or the cubic octo strut and then you can attach i-beams to the node and once you do that it builds like crazy. Some practical applications, you can stretch the XL girdersegment out and use solar panel addon to make light weight panels that hog about half the number of clock cycles that the gigantor panels do. The Monopropellant tanks were used in the my grand kerbol system rounds craft that was Xenon driven The inline space plane docking port was also part, Since the core only had docking ports for fuel i needed a part that could get crew to the 100 crew starship. One a nacell arn it was the part that rooted the nacell and directly fed crew into sp2 crew used as the arm or linker to the craft core. The inline clampotron actually i never use, not because its a bad design, but because i had trouble linking it. I have used it to play around but i basically have a station lander design that i have settled on and i am more about increasing efficient utility, e.g. maximum science per unit time, that creating steam punk space craft. The other things you mention, all used. And don't worry that you don't have an idea right now that uses the part, as you explore around you may find places or applications where it might be important, for example a refueling station on a small satellite.

phys.org/news/2015-09-entanglement-lifetime-magnitude-coupled-cavities.html Other than photon pairs, practically using entanglement has its share of problems, one of which is keeping members of the entangled pair from interacting. Suppose i wnat to send an encypted message to someone, but i need to create a code each time. I can send/give entangled particles to that person in advance and then interact with those particles exactly when i send the message, then only two people could know the cipher.

Patchy reionization and the oldest galaxy in the visible universe
PB666 replied to PB666's topic in Science & Spaceflight
http://www.csmonitor.com/Science/2015/0909/At-13.2-billion-years-this-galaxy-is-almost-as-old-as-the-universe-itself This source is a little bit better written. -
yes, assumming thes were virtual particles, you might be able to accelerate them, not withstandin the consevation argument, but they could never supply the energy to accelerate them. In theory once the quantum pair is generated, you put energy in to stabilize them and separate them. The you put more energy into accelerate them. With out the energy input they vanished back into vacuum space. you would have to be very fast though, because these appear at 10E-43 second and are gone just as fast. The pair are actually not free, the energy you put into capture them is minimally two photons of high energy. you only get that energy back if they annihilate. I should add that this is theoretically possible because it is possible to create high energy photons without using antimatter as the source, and you coukd calculate the minimum hv require for pair production, but if you are dreaming, why not create a proton anti-proton, as these have more momentum your push off mass will be be greater. in this dream you calculate the spectrum and perfect incident angles you create two photon sources, you incrase hv a little over desired you scatter the frequency a little therefore creating a perfect beam the collision happens every time, followed by two massive EM fields that project the charge to contaiment field. They are kept only momentarily and fed into the particle accelerator, the ship is very long and the charges are accelerated GeV energy. There is only one problem with the dream. We don't know how to make the proton making photons by any conventional method, the photons themselves are highly coorosive and prefer to interact with matter, so. The other problem is high a accelerators are heavy abd need alot of cooling which means alot of mass.

Math and science skills as adults are protective
PB666 replied to PB666's topic in Science & Spaceflight
I need to correct this, though why is a matter of compulsion. An Ox is the proper name of Bos taurids including T1 taurids which we mistakenly call cows. The Auroch, Bos taurus premigenious is properly the European Wild Ox in its description. If i was to refer to a tibetian domesticated ox, thet would be a yak. The indian domesticated ox is the zebu and other varieties. The fact that we don't use the word Ox at all levels of American or English societies show the pervasiveness of colloquialisms. The tradition of the use of the word cow comes from the fact that a herd of cattle, used to define livestock, is largely made up of females, males between one and two years of age are culled to keep meat quality from declining. The females are allowed to age a produce offspring or milk. -
Math and science skills as adults are protective
PB666 replied to PB666's topic in Science & Spaceflight
The problem in the US, is that we are not all created equal in the eyes of the collective educational system. Some districts do not get sufficient funding, for example to replace text books, in the case of one school district here they were using they same text books for 40 years. (and 30 years ago, that is the books of people who will start retiring soom, I actually saw the highscool texts and they were in appaullingly bad shape) The legal system finally intervened calling the educational system unconstitutional but reform has been slow beyond belief because the general attitude of conservatives in the state is that if peoples kids are not being educated its their own fault. The tech industry has basically said, if you want us to move jobs here you better start teaching STEM. And so NOW their is an economic incentive from the urban conservatives, but rural conservatives still hold on to a 19th century value system. So who is taking the high TECH jobs, here in the US many of those jobs are being assummed by people who are educated overseas, in the biomedical science the overwhelming majority of PH. D. candidates are either non-citizens or the children of immigrants. This does not bode well for the countries future, in comparison with the 60 and 70s there has been a massive decline of participation. So the question is why has this occurred. The major reason is a relative decline in resources going to publically funded science relative to GDP, highly competitive funding and unreliable incomes. -
Dark Giant may be lurking beyond pluto's orbit
PB666 replied to PB666's topic in Science & Spaceflight
It would be relatively stationary compared to another planetary reference point like jupiter. But since jupiters orbit is rather slow also we would use then gas giants collectively as refences points and star close to systems plane. This is a moot point anyway because this region of space is cold from our pov, the solar wind has spread out, slowed down, moisture sublimates, and pluto is covered with essentially solids of STP liquids and liquids of STP gases meaning that the background is fairly low in the IR spectrum. Any exothermic body, a large body with a higher NTO to surface ratio will have a surface blazing IR relative to the background and will be moving relative to the gas giants and the starfield. Even a dyson sphere, assumption being they are converting usable hv to power is going to output IR as a byproduct of the coversion. IOW there is no way not to be visible except to be nuclear and gravitationally dead. -

Well, i mean what can be said, looking at myself, if everyone were a programmer how screwed up the world would be. I mean thing of the 2008 financial crisis on speed and steroids. Oh and lets make sure they all have physics ph. D.s. That would never go wrong. lol. There was an article the other day that basically argues that great thinking lead to neuroticism. lol. -
Yep in single core systems its a psuedo lockout when data is incoming.

Patchy reionization and the oldest galaxy in the visible universe
PB666 replied to PB666's topic in Science & Spaceflight
thanks againI will synopse this a bit. The lyman series of are the UV emmission spectrum of hydrogen. In the lab alpha is 1216 Ang which translates into 121.6 nm, which approaching the vacuum UV, this stuff not the good UV but is the stuff that will give you a sunburn. They found what the think is this ly alpha at 1177.6 nm. The degree of redshift is a 8.6 (calibrated) fold factor which is the highest degree of redshift for any celestial object in the visible universe. This means that it is moving away from us faster than most other galaxies and possibly all other known galaxies. Because we assume inflation was uniform and because this object should be comoving better relative to surrounding mass, we then have to assume this galaxy is farther away than galaxies with lower redshifts or z As the universe cooled plasma hydrogen in form of proton and free electrons, deionizing the universe permitting CMBR. This produces nonionizing radiation. The theta between comoving gas is relatively large which means that the light is rather quickly redshifted relative to the gas it moves through that gas at greater distances. In quickly redshifting it is less suceptible to absorbtion from gas or plasma. The ionization of intergalactic gas is not over. Hydrogen stars are very hard to form because they lack nuclei, but dense pockets gas kept apart by motion are begiining to cool, and friction of swirls is causing circular motion to abate and hydrogen collapses into large first generation stars. These stars, because of their inherant size have a very hot light producing surface which translates into much more blue and UV light than our sun. The galaxy EGSY8p7 falls into this catagory. When these stars formed they send large amounts of high velocity plasma and UV, and x-rays into the surrounding media, which cause a reionization and this process prevents us from seeing the very oldest stars, because at frequencies higher than CNBR much of the universe is becomes opaque. Except an area between our galaxies comoving reference frame and this ancient galaxy, EGSY8p7, that for some reason has not greatly reionized or is less dense in gas. It is more or less looking down into a pit in a media composed of plasma. So the question why is this area less ionized and other areas more ionized. Previous reports last year claimed that polarized light in CNBR indicate structure, possibly as a consequence of imperfect inflation. Critques argue that this is either not true or that the signal to noise was to low for the conclusions the authors drew. So this paper suggests in a different way that long range gas densities were not uniform. EM in the universe should have been uniform and thus piar production should also have been uniform. However this paper indicates the may been non-uniformity. So what are the critiques, could this galaxy not be closer and moving in the comoving frame and away from us. Absorption spectrum of skyline molecules. They use another spectra IRAC[3.6]-[4.5] to suugest a redshift of 8, making it older than other galaxies at the previous limit of 7. The 11776 Ang value they claim is sigma =7 which using the monte carlo markov chaim seems reasoable given the distribution and signal to noise. The critque is that the signal is on a rather limited number of pixels, and one cannot claim at that level independency between adjacent pixels. Non-independcy can tend to amplify statistical diiferences by making power look greater than it is. So they did randomly sample 1500 spots looking for a similar line and found none, so the background values i hoped are the basis for their monte carlo seem reasonable, the issue then is how independent can 11 clustered pixels be, given that this is a keck ground based telescope observation. Another critique is that previous researchers got it wrong, taking in adequate measures to find emmision spectrum bands in galaxies potentially more redshifted than 7. The range of equivilent width values of. 17-42 Ang makes this not only one of the oldest but one of the brightest Z>7 galaxies and is comparble to galaxies younger than the reionization < 6.5. but studies of redshift 2 galaxies shows a higher range of EW suggesting that light from the most distant galaxies is somewhat attenuated. I suppose this opens the door with space telescopes, better infrared equipment in a cooler environemnt better signal to noise and even more red shifted galaxies. Some of the physics for deionization and reionization is likely to change. Technical critique, the paper lacked an abbreviation list, but they use a rather large number of obscure abbreviations, its actually the first time i have seen references abbreviated in this style and was a bit disconcerting. The lyman alpha wave length was not given, for a broader audiance relavent spectral lines should have been illustrated, this may seem trivial, but they specifically select certain bands over others because of post emmision contamination and absoption potentials. It would have been nice to see a table or figure detailing what those were. The z-value calibration method was only breifly detailed. The skyline contribution while specifically defined, generally was not well defined. Figure 1 legend marginally explains the figure. -
