    But, the breakdown of raw elements into the dirt, with water and carbon (along with other chemicals) being pupmed under pressure into the churning mix is basic science, whether it will work in the way I am proposing will be up to the expert opinion of a chemist, which is why I signed up to join this forum. I am NOT a chemist. My major two sources of science that I respect the most in the world are two people I follow on YouTube, Neil DeGrasse Tyson great astrophysicist/teacher/public science enthuser and fantastic explainer and Yuri Kovalenok, a brilliant Russian physicist and I believe one of the smartest guys in the word in his ability to attract attention to science for people who aren't scientists or otherwise big science people through turning his physic notes into cool T-shirts and other items.

    I was hoping a professional chemist would glance over the idea and vet the idea on the merits presented as to the likelyhood of success.

    Just presenting the idea, if not viable in either instance helps juggle the collective brain to think outside the box and find some other variation or go in a compleety different path. However, I would more rather that it work without my seeking a patent myself for the system or claim it as mine. I would like to clean coal. many peole are against it the way satan is against Jesus Christ and they will have no talk or discussion on any clean coal idea.

     

    Well, you've had your answer from the people here. Your idea about making soil fertile by passing CO2 into it is misguided and won't work. Plants do not take in CO2 via their roots but via their leaves. As for "....the  breakdown of raw elements into the dirt, with water and carbon (along with other chemicals) being pupmed under pressure into the churning mix", that does not describe anything coherent enough to comment on.

    Is it possible for a coal plant to pipe some of it's exhaust into a greenhouse-like structure filled with worthless mineral deficient dirt and infuse it with carbon to the point it turns into valuable soil capable of growing food with?

    Or if the greenhouse-like structure was filled with fast growing trees, as part of a for-profit tree farm, would this aid, stunt or be neutral to their growth?

    Passing CO2 over poor soil won’t improve its fertility, but increasing the CO2 content of air in a greenhouse does accelerate growth. This has been widely done for years in the Netherlands, where a gas engine is used to generate electricity to light them in winter months, exhaust is used to promote growth and waste heat to warm them. This is done commercially to produce tomatoes, capsicums etc all year round for supermarkets.

    Well you should care.

     

    Heat capacity is the capacity to absorb heat, yes.

    But once absorbed you want to store it and finally retrieve it, not loose it or waste it.

    This is where heat conduction and heat transfer coefficients become important.
    Thermodynamics forces you to store heat energy at a higher temperature than the surroundings you want to keep warm.
    Note this is different from chemical, mechanical potential or electrical energy.
    But you want to release it gradually as slowly as needed otherwise much goes to waste.

    The design of electric night storage radiators has greatly improved over the years as manufacturers slowly recognised this very important factor.

    Seth's cast iron Rayburn was a classic victorian implementation of this knowledge as were the massive cast iron fireplace surrounds they used to install. +1

    I still have those massive iron fireplace surrounds in the upstairs bedrooms in my late Victorian (1897) house. I was surprised to find, when planning some redecoration, that the mantelpieces are all magnetic.

    here are links directly without any external link to files.

    Both San Antonio TX and Bismarck ND have the same type of soil - ustolls mollisols. But in San Antonio the average annual air temperature is 21°C, in Bismarck - 6°C. Completely different temperatures but the same soil! But the average annual wind speed and atmospheric pressure are the same (12km/h, 1017mbar). You can see on the map the soil of ustolls from texas to north dakota. So this is proof that air temperature does not affect soil type!

    Then what about Fayetteville AR? Fayetteville is not located near the Appalachians, but has the same type of soil as Richmond and Montgomery!

    Are you seriously arguing that because the average air temperatures are different, there can't be any effect of air temperature on soil formation? Why consider the average? Why not the annual range, for instance? Or the difference between day and night? Aren't these more likely to affect soil formation and structure, via expansion and contraction, effects on moisture content, freeze/thaw cycles and so forth?

    (Text of article below video)

    I find some of the scenarios of survival presented in this article bordering on absurd.  And the notion of "rebuilding." Rebuild what, exactly?  With what food supply?  Newsweek does its readers a disservice, giving a false idea that a few places blessed by distance from strategic targets, favorable wind patterns and rain shadows, and what? A decade of canned goods for all? An amazing supply of engineers, educators, physicians, stored gas and diesel and heavy equipment? will somehow rebuild civilization as we know it.  

    My favorite expert quote in the article was:

    Days?  Really?  I rarely use emojis, but....😂

    It gets better here:

    Sure, pal, heading to Home Depot as soon as the mushroom cloud s appear!  Oh, wait, the intense multiple EMPs fried my car's electronics.  

    More handy tips....

    Aside from the idiocy of thinking you can drill a deep aquifer well after the fact, someone needs to point out that that east-of-Rockies rain shadow zone (where I live) is bristling with missile silos and heavy bomber bases and other attractive targets to an adversary in a nuke exchange.  And lots and lots of loose dry surface soil...

    the formation of indium nitrate using indium metal and concentrated nitric acid 

    As you can't be bothered to explain what the hell you are trying to do, or even to converse in complete sentences, I've now had enough of you.

    when you draw the displayed formula of a molecule, does it matter how you draw it as long as each atom makes the right number of bonds?
    for example, does it matter what the molecule C3H4O3 looks like as long as the carbon makes 4 bonds each, the oxygen 2 and the hydrogen 1?

    Depends what you are trying to do. If you just want to show what is bonded to what then it doesn’t matter, but if you want show spatial relationships then bond angles can become important.

    As I said, it's a relativistic correction to the energy levels. That's it. There's no Bohr-atom extrapolation to the speed (which is an overused crutch, common in undergrad explanations), or relativistic mass invocation.

    OK but can you provide some insight into what is it that makes the correction significant for atoms with a high nuclear charge? Because that seems to be the point the undergrad explanation tries to address. 

  14. 7 hours ago, swansont said:

    Do they have one? Can you cite any evidence?

     

    Most treatments of this that I’ve seen are careful to note that this is a relativistic correction to the energy level, and make no claim regarding either the speed or mass.

    No doubt that would be the more rigorous way to treat it, the concept of speed being a bit dodgy in such a context. But it was used to explain at undergrad level why these corrections are only required for atoms with vey high nuclear charge. How does this arise in the more rigorous treatments you have in mind?

    The KG equation does not represent electron clouds. It represents the dynamics of creation/annihilation of charged/neutral, as the case may be, spin-zero particles, as @Markus Hanke told you.

    Very internal electrons might. I'm not sure about that now, but I'd expect them to have a sizable fraction of the speed of light as expected value.

    The undergraduate explanation for the colour of gold is based on electrons in atoms with very high nuclear charge moving at such speeds and thus, in terms of non-relativistic QM, having a greater effective mass than they would otherwise:

    Water is intimately connected to Devine. For centuries humans have used water as a medium for human encounter with the divine. These waters are a getaway to God’s blessings. Bring the presence of our creator all around you through daily prayer and reuse it. This water is sacred and magical!! It is sourced from the most sacred holy places on earth, the Jordan River, Lourdes Shrine, Guadalupe, Vatican City, Mecca and many other places. We decided to source this water from all these sacred places to bring you the most sacred water on earth. No matter what religion you practice this water will bring the presence of God around you.

    Jordan River
    For centuries, baptisms have been performed in the Jordan River, considered holy by many religious communities. As the site of the baptism of Jesus Christ, the Jordan River is the source of all holy water in Christianity and has for centuries attracted pilgrims from across the world.  This is where John the baptist did his sacred work.

    Lourdes Shrine
    Lourdes water is water which flows from a spring in the Grotto of Massabielle in the Sanctuary of Our Lady of Lourdes, France. The location of the spring was described to Bernadette Soubirous by an apparition of Our Lady of Lourdes on 25 February 1858. Since that time, many thousands of pilgrims to Lourdeshave followed the instruction of the Blessed Virgin Mary to "drink at the spring and bathe in it".

    Zam Zam Water
    Zamzam water is believed to be blessed holy water. The source of this water is the Zamzam well is situated within Masjid-al-Haram in Mecca, Saudi Arabia. The well is located 20 metres east of the Al-Kaaba, which is known as the holiest place in Islam. Zamzam Water has been scientifically proven to contain very high levels of Calcium and Magnesium, which can help decrease fatigue. This also provides the water with healing qualities thanks to high fluoride levels similar to conventional medicine properties.

    Vatican City
    This holy water is collected at the basilica of Vatican city. Blessed by the pope and filled with blessed water directly from St. Peter's square at Vatican City. This water has been blessed during public blessing in Saint Peter by Pope Francis.

    Guadalupe
    Our Lady of Guadalupe is the perfect vessel for holy water used for personal blessings throughout the day! Exported from Mexico City, where the most important shrine dedicated to Our Lady of Guadalupe is located.  The basílica of Our Lady of Guadalupe or Villa de Guadalupe receives 20 million tourists and pilgrims a year who visit the sacred place where a vision appeared to Juan Diego in 1531 in the hill of Tepeyac.

    You mean "divine". "Devine" is a person's name. 

    Your post reads like a rather incompetent attempt at a marketing scam: incompetent because there is no link to whatever business is hoping to profit from selling the stuff, and a scam because it claims bogus special virtue in water from particular places. (The claim about the Jordan is entirely false).  

    At least as far as the references to Catholic locations are concerned, holy water in the Catholic church is simply water that has been ritually blessed by any priest, for use in various rituals in which water plays a symbolic role. It can be ordinary tap water, salt usually being added to suppress algal and bacterial growth. It is used in baptisms, in holy water stoups at the entrance to churches, in the "Asperges" at the start of traditional High Mass and so on. There is no need or expectation that it come from anywhere special.

    Sultan Bahoo, the leader of Mystics, the beloved of Allah and the Sultan of 𝐹𝑎𝑞𝑟 is stationed at the highest and the ultimate rank of ‘the master of worlds’. He is the perfect spiritual guide possessing the absolute light of guidance. Sultan Bahoo travelled all his life to guide the creation towards Divine gnosis. Being the perfect manifestation of Divine attributes and Essence, he elevated the seekers of Allah to the levels of becoming immortal with Allah after annihilating in Him in just a single glance.

    Commercial link removed by moderator

    Commercial link removed by moderator order is called Qadri order and Sultan Bahoo’s order is called Sarwari Qadri order. You must have seen similarity in names. Well Sarwari Qadri order is Qadri order. He composed and put together the actual Qadri order and renamed it as Sarwari Qadri order. As any order which becomes famous is later on after many years cashed on by fake guru’s. Therefore to avoid innumerable fake followers and guides, the famous Sultan Bahoo renamed his order as Sarwari Qadri. It was to divert true followers onto the straight path and left fake guru’s to use name only. The essence remains in Sarwari Qadri order to date.

    It is a fact that the satanic powers prevailed in the world that was taking Muslim umma into darkness. However, the Light of Allah always wins and this time it was through the spiritual order of Sarwari Qadri of Sultan Bahoo that serves as a savior to date through his spiritual descendant Sultan ul Ashiqeen.

    But the most common question swirling through people’s mind is, “What is the phenomenon through which Light has always swayed the darkness? The answer lays in human history. In fact, Allah has never left His creation alone into the deceits of Satan. Thus, during every era of darkness, Allah almighty, the most Beneficent blesses mankind with His Prophets and Saints.

    Likewise, in the late 1630 A.D Allah Almighty blessed the world with his Sufi Saint who was born to guide people towards Faqr which is true heritage of Prophet Mohammad. He was none other than Commercial link removed by moderator Hazrat Sultan Bahoo (ra). He was born on Thursday, the 1st Jamadi-us-Sani, 1039 Hijri i.e. 17 January 1630 A.D. He was born at the time of dawn, in the reign of Mughal emperor Shah Jahan in Shorkot, District Jhang, Pakistan (then India).

    Sultan Bahoo is one of the most popular saint of Islam. He preached the teachings of Prophet Mohammad pbuh and his heritage of Faqr. For this purpose, he spent his entire life to grant spiritual beneficence to the seekers of Allah so they attain closeness to Allah. Even today people beg at Sultan Bahoo shrine for spiritual progress while others pledge allegiance to his spiritual descendant Sultan ul Ashiqeen.

    Thanks.I will have to do a little(a lot) more reading before I can ask any more questions. 

    In simple terms, the key to the momentum:position thing is wave/particle duality. The momentum of a QM entity is inversely proportional to its wavelength (de Broglie's relation), i.e. proportional to frequency, while the probability of detecting the entity at a position is determined by (the square of the) amplitude of the wave. 

    If you have a QM entity represented by a pure sine wave, it has only one frequency component, so its momentum is determined precisely. But a sine wave extends throughout space. So you have no idea where it is. Conversely, if you have a superimposed series of waves of different frequencies, with phases aligned to interfere constructively at one location, then, because of the frequency differences, as you move away from that spot they will start to interfere destructively. So then you have a situation where all the amplitude is in one location - the position is well-defined - .............but you have no idea anymore what the momentum is, because it is composed of lots of different frequencies and hence momenta.

    This idea of adding waves of different frequencies to obtain various non-sinusoidal waveforms is familiar to radio and hi-fi engineers. It's not a QM idea. For instance the reason why you need good high frequency response, way above what you can hear, in an amplifier is to reproduce transients faithfully, because those require a complex mix of frequencies including very high frequency components. 

    The special ingredient in QM is de Broglie's insight, associating momentum (p) with wavelength(λ) : λ=h/p .  (h is Planck's constant).

    acceleration= change in velocity/time taken?

    No, that won't help you, because while you are told the acceleration you are not told the velocity. What do you know about this scenario? You know distance and acceleration and you want to calculate time. 

    So the formula you need is the one that relates distance, acceleration and time. If you know two of them, and you do, you can find the third.

    A student predicts that a steel ball dropped from rest from a height of 2 m will hit the floor
    after 0.63 seconds. In their calculation they used an approximate value for the acceleration
    due to gravity of g = 10 m/s2
    .
    The accepted value for the acceleration due to gravity is g = 9.8 m/s2
    .
    This means their calculated time will be:
    A. unaffected
    B. too long by about 1%
    C. too short by about 1%
    D. too long by about 0.2 seconds
    E. too short by about 0.2 seconds

    This question clearly prompts you to do the calculation. You need the appropriate formula involving acceleration. What is it?

    When the switch is on, 10 Amperes flow trough it.
    When the switch is turned off, there is arcing between its contacts.

    Added resistor to circuit, consumes 0.025A tiny current.
    When the switch is on, 10 Amperes flow trough the switch.
    When the switch is turned off, is there arcing between its contacts ?

    10K.jpg

    I seem to recall the use of a capacitor in conjunction with a resistance, to suppress arcing in the switching of electric motors. But that I think is to lessen the inductive spike when the current is interrupted. In a circuit with a simple resistive load I'm not sure what would make a difference.

    The ideal case would be a simple DNA vaccine-style system, which would allow for wide-scale implementation;

    As to why not to use preventative measures, well we have already kind of failed there- lead water pipes, mercury in seafood, platinum in soil... the fun stuff (ie we -as a global civilisation- are veery bad at preventative measures)

    Most importantly however- why not? Some heavy metals have zero safe dose, and there will always be minute amounts in water&food simply from geology- as we live longer lives, there are indications heavy metal accumulation is among the processes that cause aging as we know and fear it (eg cognitive decline, chronic inflamation).

    Have we failed? Lead water pipes are removed nowadays (unless safely passivated by hard water deposits, as in my house), lead is no longer in petrol, Hg in seafood is a recognised issue and in consequence is not generally a problem........  I think it's a mistake to tot up the various past practices that we now recognise to be risky and label them as "failures", when actually they are successes, in that we've learnt to stop them.

    But your question remains a valid one in principle, of course. Let's see what the biologists have to say.
