Draft Definition and 40 Threads

Hello again! I've found the capybara's EMA to be 0.71. Their mass to be 55kg. And their average speed to be ~3.0km/h. I want to figure out how many capybaras it would take to overcome Friction * Normal force of ~125,000N. How would I go about doing that...

The note is entitled: Evaluation of a Class of n-fold Integrals by Means of Hadamard Fractional Integration. 4 pgs pdf format. I assure you that you need not know anything about fractional calculus at all to understand this note that Howard Cohl helped me with. We only use a single...

There is a draft of Srednicki's QFT book available for free online (here: https://web.physics.ucsb.edu/~mark/ms-qft-DRAFT.pdf). I have a book voucher and, since I couldn't find it in the library, was thinking of buying it so long as the content of the book was sufficiently better (i.e...

This discussion relates to another thread on the feasibility of operating a nuclear reactor on Venus. https://www.physicsforums.com/threads/could-a-high-very-high-temperature-nuclear-reactor-operate-in-venus.1003619/ Venus represents a hostile environment with a surface temperature of ~470°C...

I enjoyed a lot the three first volumes of Zeidler's planned series of 6 books on QFT. Unfortunately, he passed away too soon. However, it is clear from reading the first three books, that an outline of the next books in the series was already planned. Is there a draft, containing the basis of...

Hi there people, I am Leroy Leon, a film maker and playwright in Nigeria, and I am writing some science fiction films and I need answers with questions on Aerodynamics, slipstream and drag. So, my question is, if I want to create a land vehicle that can travel at hypersonic speeds, the...

Ok so I'm kind of concerned here. I turned 18 May 19th this year and I just learned about the importance of signing up for the draft within a month of your birthday. Am I just screwed on some scholarships now or is there any way to fix this.

Hi You know draft Tube after a Turbine decreases velocity and increases head of flow (it changes kinematic energy of flow to pressure energy). It is used at outlet of turbine to increase pressure head from sub-atmospheric pressure to zero. Now this is the question: Why is pressure at the outlet...

I'm working on a science fiction novel, so feel free to ignore reality if you bother to answer this. In my book (rough draft) I was using laser beams to transfer data. Essentially imagine a relay of nodes between the Earth and Mars. Each node contains at least one (and probably more) laser beam...

Homework Statement ship arrives from the Atlantic to the Baltic sea. How much does the draft of the ship deepen due to the saltyness of the water... density of atlantic water = 1027kg/m^3 density of baltic water = 1005kg/m^3 at these depths the crosssectional area of the ship can be assumed...

Work output(deal) for a hydraulic machine per kg of incoming fluid is V(TANGENTIAL)*SPEED OF BLADE (assuming zero out swirl velocity. Draft tube causes static pressure ont runner outlet to fall below zero. Thus available head is increased by an amount equal to this drop. But power output from...

From, http://www.ibtimes.com/researchers-release-first-draft-open-source-tree-life-23-million-species-organisms-2105757 In a project funded by the University of Michigan and the U.S. National Science Foundation, researchers from 11 different institutions have finished creating the first draft...

This is a very rough draft of my statement of purpose. The plan is to use this as a base and customize it for different programs to include why those specific programs will help me achieve my purpose. The conclusion is missing because that will be specific to each program I'm applying to. All...

Draft re Ricci vs Riemann tensors This one is really just the beginning of a musing. I can't even remember if I came to any conclusion or just forgot about it. I started a thread in Jan 2014, a couple of months after this blog post, on the related issue of what the physical significance of...

Homework Statement The oil drum floats in such a way that one circular end is always directly up. The total mass of drum is 200 kilograms. The drum has a cross-sectional area of 0.4 m2, and the North Sea is level. What is the draft (the distance from the surface to the deepest point of...

Here is your opportunity to weigh in on one of the Fukushima issues. First link is the study and second link discusses the comment process. http://pbadupws.nrc.gov/docs/ML1313/ML13133A132.pdf http://pbadupws.nrc.gov/docs/ML1317/ML13175A104.pdf

First, here is some context for a series I'm writing. The main setting for tomes 1-11 (I'm writing tome 12 now, which takes place after the 4th generation main character graduates from her music PhD) is an otherworldly city surrounded by a LHC-like particle accelerator whose radius is 2π km, and...

Congressmen, Why have you allowed such a massive budget deficit to persist? I can only see three outcomes for such a course: 1) Unprecedented budget cuts. 2) Unprecedented tax increases. 3) If neither above, the destruction of the value of the dollar as an international currency. So what...

Dear friends of MHB in this thread some aspects of the difference equation of degree greater than one are investigated. For size limitation the tutorial is divided into several sections. As for the part I, suggestions, observations, requests of clarification and improvements are welcome...

Dear friends of MHB some months ago I wrote for MHF a tutorial on the Difference equations and the reason of that was the difficulties I noticed in the treatment of difference equations, an important chapter of Discrete Maths that [may be...] is a little unfairly undervaluated. Request by the...

The Draft of Poster of New Fusion Concept that I am going to represent at 53rd Annual Meeting organized by Plasma Physics Division of American Physical Society (attached file .zip) Without drawings yet but I will complete drawings till mentioned event.

Homework Statement Consider a large cargo ship, with a steel (density = 7.5g/cc, 7500kg/m^3) hull. If I ignore the mass of the front and back of the ship, how far into the water (height) will the ship sit? Homework Equations density = m/v Force(buoyancy) = (density of fluid)(volume...

I ran across this article from a Korean newspaper. (don't have any link to an English translation of the article) The subway authorities in Seoul will be testing wind generators that will be placed right outside subway vents. The idea appears to be that since the enormous draft created by...

Hello! :smile: I have one mysterious question. I have room 25 m2, and I want to made draft, by opening one window and my door to be closed, so I will have closed space with only one window open. What is actually draft? Is it same with wind? Draft = circling of hot and cold air? Thank you.

I am wondering if: 1. Is it possible to design such system? I am trying to induce the Aluminium Tin, then deflect it using a positively charged metal plate. 2. If so, what is the cost needed? Let say I want to deflect the tin for about 5cm from the center, and the size of the design should...

---To find the dimensions of a DRAFT TUBE------- I hav a doubt regardin fluid mechanics... >>Say I have a draft tube which is like an inverted frustum of a cone. >>I pass a fluid of volume "V" ,and this fluid helps in balancin a ball of mass "m" at the outlet of the tube . >>The...

All these disoriented lunatics are yapping about the selective service being resumed, so I'd like to echo a spokesman's words: there is no draft! Though for some reason, Google Trends has internet news references to "selective service" at an all-time peak about now...

I don't ever want to see another draft in this country. "WASHINGTON (Reuters) - An influential Democratic lawmaker on Sunday called for reinstatement of the draft as a way to boost U.S. troop levels and draw a broader section of the population into the military or public service. U.S. Rep...

In the US, there's something called the Selective Service System. I think this quote from their website sums up quite well what they do: Basically, if there was ever a draft, this is the list of potential draftees. More information is available at http://www.sss.gov/Default.htm. Here's their...

What are people's opinion on the reintroduction of the draft? Is it likely to happen? Will you support it if it does?

"The US military is planning to deploy robots armed with machine-guns to wage war against insurgents in Iraq". http://news.bbc.co.uk/2/hi/americas/4199935.stm

"Draft"=Army of Slaves It just occurred to me, and maybe I'm getting a bit too far out there but doesn't a drafted army seem a lot like an army of slaves, I mean if you don't go to war willingly is this not the basic idea of slavery? You say a person could choose to go to prison or leave the...

Stop loss orders are a back door draft. Clearly there is a shortage of soldiers. In fact, IIRC, Bush was just as certain that Saddam had stockpiles of WMDs, that the war would be quick, and that the war was already won, long ago.

Just curious about the contents of the bill (or proposal, or whatever it's called) about re-instituting the draft and whether women and men would have an equal chance of being drafted under it's provisions.

Rough Draft of Speech Done! Since so many of you guys have been helping me with my understanding of certain areas like Gr SR LQG and QM I figured you may want to see how your work payed off... here is a link to a copy of the speech...

Draft proposal - Women get ready for your equal opportunity! SB 89 and HR 163 are pushing for the draft and expected to come into play, if they are passed, in January 2005. I'm personally against a drafted military, only because I believe it much weaker than a volunteer service.However, if it...

hey...i am ****ed for life... i go to a UC and i got caught plagiarising on my english essay, but the thing is its only the rough draft and the final draft is COMPLETELY different and in my own, but still the proff turned it into the board members and i got an automatic F for the class...

I see no real urgency for a draft, but should N Korea fire up, or China attacked Taiwan, that would certainly change things, wouldn't it? Off to war we may go.

Draft poll... 1>Did you support the war in Iraq? 2>Do you still? (if applicable) 3>If drafted, would you show up, or dodge? 4> Is your reasoning based almost fully on the Iraq war (if you would dodge)? 5> anything else you want to comment on?

I'm not sure if this is true but a friend told me a friend of his (just over 18) received a draft notice to report to the nearest induction center. The reinstitution was bandied about in the press for awhile but I didn't think they would do it and now it seems to have happened with hardly, if...
