William Oughtred and others developed the slide rule in the 17th century based on the emerging work on logarithms by John Napier.
Ever hear of a "sector". It predates the sliderule and could do some calculations a sliderule can't.fingersabacusslide ruletables
Analog would be like a sliderule which is based on logarithms. Digital would be like a calculator.
Modern electronic calculators are small, digital, and usually inexpensive devices to perform the basic operations of arithmetic. Before we had calculators we had slide rules. In 1632, the circular and rectangular sliderule was invented by W. Oughtred. In 1885, Burroughs filed his first patent for a calculating machine. However, his 1892 patent was for an improved calculating machine with an added printer. William Seward Burroughs invented the first practical adding and listing machine.
He did not invent any computer, a computer is capable of automating a calculation without human assistance.What he did invent was the sliderule, an analog mechanical calculation aid. He was most likely after a faster way to do multiplication and division, as that is the main thing a sliderule does.
That is a complicated function of:height/depth of burstdistance from burstneutron flux density and spectrumthermal pulseovercast, if airburstdensity, etc. of material around burst, if subsurface burstmechanical condition of marble prior to burstchemical impurities in marbleetc.Without more data than is given in your question, no real answer can be given. I would suggest doing some research yourself on nuclear weapons effects.A good place to start is "The Effects of NUCLEAR WEAPONS" Edited by Samuel Glasstone. I have a copy of the 1964 edition with the weapons effects circular sliderule that I paid half a dollar for at a library discards sale (the sliderule alone is worth well over 20 times that, even though my book has damage seriously reducing its value on the market). If your library doesn't have it, request it on interlibrary loan. (I don't think you can get the sliderule anymore though)
That would be an Abacus.Depends if you mean the electronic calculator or not? Before we had calculators we had slide rulers. In 1632, the circular and rectangular sliderule was invented by W. Oughtred. William Seward Burroughs invented the first practical adding and listing machine. Burroughs submitted a patent application in 1885 for his 'Calculating Machine' and the patent was awarded in 1888.
That would imply a blast radius of roughly 100 miles. Assuming a maximum overpressure of 1 psi (minimal structural damage to average construction) and using my Nuclear Weapons effects circular sliderule: I get a minimum airburst yield (at optimal altitude) of about 340 MTons (off scale on the sliderule but easy to extrapolate the 2 orders of magnitude needed). No bomb of this yield has ever been built. If one was and detonated the blast radius would probably be somewhat reduced, because in this yield range most of the blast energy gets expended upward and blows the top of the atmosphere into space. Many bombs in roughly the 1 MTon range could do the same damage much more economically and effectively.
