  1. In Australia in the mid 70's our courts revealed that there was no requirement for truth in political advertising. This was pre Australia Act 1986 so there was no rule requiring truth in UK political advertising either, unless one has been introduced since then. Around the same time the wrestlers from our 'World Championship Wrestling' were all required to join the Actors Equity Union. Just to be consistent, why not flush your double jeopardy laws down the toilet along with your constitutional values and what little remains of your political integrity and honesty.
  2. In Australia in the 1970's the participants in our 'World Championship Wrestling' were all forced to join the Actors Equity union. Also around that time a court decided that their was no requirement for truth in political advertising. So how could Trump be the heel if he is hated by the spectators who support the others and hated by the spectators who support the heels, when all he says is 'fake news'? https://en.wikipedia.org/wiki/World_Championship_Wrestling_(Australia)
  3. It also mentions a Lecomte du Noüy Tensiometer in 1930 so it's probably an old style Deflectometer. https://en.wikipedia.org/wiki/Tensiometer_(surface_tension)#Du_Noüy_ring_tensiometer
  4. A function is an equation and a derivative or an integral are both manipulations of the function.
  5. I identified the relevant pages (the actual PDF pages not the book pages) in my original post and hi lighted the relevant sections on those pages so you don't have to read the entire book. A derivative in its most simplistic form is the application of n*x^(n-1) for all x in quadratic equations in the form of a*x^2 + b*x^1 + c*x^0 = 0 i.e. ax^2 + bx + c = 0. The first derivative of this equation is 2*a*x^1 + 1*b*x^0 + 0*c*x^-1 = 2ax +b. The first integral of 2ax +b is ax^2 + bx + c.
  6. An integral is just the reverse of a derivative. Reference H.J.Keisler "Elementary Calculus an Infinitessimal Approach" (992 pages) PDF link: https://www.math.wisc.edu/~keisler/keislercalc-03-07-17.pdf At a conceptual structural level improper integrals in physics can be piecewise continuous integrals, with limits from +infinity to -infinity, that converge. Refer H.J. Keisler, p367, Definition to p369, examples 7, 8, and 9. If they are continuous and don't converge then they are indefinite integrals which are entirely different. Refer H.J. Keisler, p370, example 10, diagram 6.7.10 "It is tempting to argue that the positive area to the right of the origin and the negative area to the left exactly cancel each other out so that the improper integral is zero. But this leads to a paradox... So we do not give the integral ... the value 0, instead leave it undefined." That doesn't mean that indefinite integrals don't play a part in our physics as an indefinite integral that cycles between +infinity and -infinity at its limits, as a sub function of a higher level function, is a valid proper use of indefinite integrals as definite integrals by change of variables. Refer H.J. Keisler, p224-5, Definition and example 8, diagram 4.4.6 second equation with u and substitute infinite limits. "We do not know how to find the indefinite integrals in this example. Nevertheless the answer is 0 because on changing variables both limits of integration become the same."

  8. Seriously I hope it's nothing like yesterdays Xkcd cartoon. https://imgs.xkcd.com/comics/eht_black_hole_picture.png
  9. The Cycloid Arc has some inherent geometric and realistic physical properties. https://en.wikipedia.org/wiki/Cycloid (1) the area of the plot, of one complete revolution of a Cycloid Arc on a 2D plane, equals the surface area of a sphere of the same radius as the Cycloid. (2) the area under the line of the Cycloid Arc on the 2D plot exactly equals the area of a circle with the same radius. A circle with the same radius and the same surface area cannot be duplicated on the surface of a sphere due to the curvature of the sphere. (3) the area above the line of the Cycloid Arc on the 2D plot exactly equals 3 times the area of a circle with the same radius. (4) the Tautochrone curve is half a Cycloid Arc that, in its physical form, has an interesting property. https://en.wikipedia.org/wiki/Tautochrone_curve Do we theoretically mistake these intrinsic properties for something other than what they really are?
  10. Larger piston sizes in 4 cylinder engines mean peak power at relatively low revolutions which is preferable for trucks. Mr Steed, from the original 'Avengers' TV show, drove a supercharged 4.5 liter inline 4 cylinder Bentley with revolutions limited to 4,000. That car won the Le Mans 24 hour race in 1928.
  11. You should also look at the Compton wavelength equations to see the relationship between the Planck constant and photons. https://en.wikipedia.org/wiki/Compton_wavelength#Distinction_between_reduced_and_non-reduced

  13. If you want more technical information Nina Byers goes into the detail in her 1998 paper "E. Noether’s Discovery of the Deep Connection Between Symmetries and Conservation Laws". https://arxiv.org/abs/physics/9807044v2
  14. There is one way to find out DrP, from the tektite link.
  15. Probably some form of Obsidian. https://en.wikipedia.org/wiki/Obsidian
  16. I don't know about the rest of you but I think that letting a heavy door slam into someone behind you, whatever their sex, is an assault as well as showing a lack of common courtesy. Also, as iNow and Moontanman know from other sites, just because someone has a first name like mine, doesn't mean that they are female.
  17. Years ago a friend had similar problems with an old laptop on Windows XP. The virus didn't encrypt anything but just displayed an impressive screen (all of the Australian state police badges and the Federal police) and totally blocked access to any programs after logging in. As the laptop was so slow I repeatedly pressed CTRL+C while logging in (straight after typing my password). When the message came up I quickly started up Task Manager (that's one of the options CTRL+C gives you) and stopped the process with the highest CPU usage at that time. I must have picked the right one because Windows Defender popped up straight away and asked if I would like to remove the virus. Hope that helps.
  18. From Google.
  19. What about the public service? Just over 20 years ago Australian politicians decided that managers don't have to know anything about what they manage, all they need to know is how to manage. Now all the technical people are contractors because the public servant bureaucrats won't employ anyone who knows just how little they actually do know because it's bad for team morale.
  20. We do know that the ratio of total universal matter calculated using the LambdaCDM model (dark matter + ordinary matter) divided by ordinary matter equals 2*Pi +/-1.1% for both the Planck and WMAP data. Highly imaginative and knowledgeable scientists would probably realize that this means, for universal calculations based on WMAP or PLANCK data, dark matter is redundant regardless of how it came about.
  21. The Taiwanese aborigines might be a good start. https://guidetotaipei.com/article/who-are-the-taiwanese-aboriginals
  22. I have an Applied Science degree and must say that the only real facts that we know about the LambdaCDM model and 'dm' is that the ratio of TOTAL CALCULATED UNIVERSAL MATTER (i.e. DM & OM) to TOTAL CALCULATED ORDINARY MATTER equals 2 * Pi +/- 1.1 % in both the WMAP and PLANCK data. Our gravitational models only operate inside a sphere and our visible universe is similarly limited so lets stop perpetually wrangling unicorns etc while bleating numerology at the only thing that makes any sense and understand that the universe may actually exist beyond the realms of our limited scientific models and the mathematics that describe them!
  23. I remember a recent discussion in Australia where it was argued that our external agencies don't need special laws to get the goods on anybody internally because an external agency just has to hire another external agency, criminal or otherwise, to get access to the information they need! Surely it is becoming very obvious that corruption won the cold war and not any particular ideology.
  24. Hmmm, in the UK the members of the opposition party vote for the party leader and the MP's only get 1 vote each, In Australia the members of the party get 50% of the vote and the MP's get another 50% (Bill Shorten only secured 40% of the party vote (Albo 60%) but he obviously has the numbers on 60% of the MP's giving him a total percentage comparable to BREXIT) and in Queensland the members of the party get 1/3, the MP's get 1/3 and the Unions get 1/3 (so the unions control the state because they end up selecting the candidate MP's). Prior to Kevin Rudd being rolled by right wing MP's and then recovering the leadership the party MP's had 100% of the leadership vote.
  25. It's probably not a good idea to use words like extreme right in the current context of Australian politics. In fact left and right have been interchangeable since that old (extreme right wing) revolutionary 'left' wing Paul Keating sold off the Commonwealth bank and started selling the national telecommunications company. Why do you think that the 'left' wing opposition party, in the past 2 federal elections, gained their lowest first preference votes for nearly a hundred years? With a 'left' wing political party whose right wing leaders have no concern over retaining public assets (mainly because they have all been sold) it is not surprising that many, the 'old left', have deserted the neo LGBTI/GREEN/UNION thug 'left' party and sought other parties lest they be accused of either being hypocrites or suffering from dementia. Also, now that the current right wing government has ejected their leftie PM, surely the opposition (or what's 'left' of them) should have a good think about ejecting their right wing leader, unless, of course, they think that a union boss should do deals with big business to trade a 2 cent per hour pay rise for minimum wage cleaners for $30K to employ someone to get that union boss elected as a politician. If you can swallow that BS don't bother to call yourself left.
