EldwinSchrodinger @ Seminar for SuccessUniversity
loving you always ♥
it was 9 in the morning and i woke up and i thought it was already 10am. i was like OMFG i'm so late for the OnlineIncomeHub seminar at URA building. and so i called Patrick and yeah we meet up at tanjong pagah before healing to the meeting venue. and yeah the boot camp lasted from 10am to 5pm in the afternoon. full day straight. business discussion on a new online income plan. and yeah entrance fee for the seminar cost s$100 for members while s$200 for non member of success university dot com.
and before the long seminar actually begins, a magician was invited to get us into the whole thingy. but god knows this magician was hell great man. card tricks to appearing money to liquid water to frozen ice in a plastic cup. yeah
guess what! Johnny's gonna launch this plan right in singapore! we're the first to hear, spread and inform people about this! oh boy i bet london and america's gonna be so jealous about it. "Why not us!" lols. and yeah we were invited to join him at his hotel for some chill out but yeah most couldn't make it. well its a saturday afterall.
guessed what. called mourinhois king and he and sengleng brought be to the rest who were at burgerking.
so these few people went

hell of a list.. so i'll just list a few down.

Capacitors. Capacitors are the most widely used power source for energy discharge experiments: From Z-pinch driven nuclear fusion to lasers, rail guns, coil guns, EMP generators and hypersonic metal forming, capacitors provide the ultra fast, extremely high power impulses required to achieve the currents to drive the enormous magnetic field these devices require. Although high performance high voltage pulse capacitors are extremely expensive, costing several thousand dollars per kilojoules, the (relatively) lower current requirements of coil guns make it possible for non pulse rated capacitors to be used on them with good results. Amongst the worst capacitors in terms of pulse performance are electrochemical capacitors (these are also very low voltage, thus being unpractical on coil guns) and electrolytic capacitors. However, electrolytic capacitors also happen to be the cheapest capacitors around, so it is not surprising that just about amateur every coil gun uses. Electrolytic capacitors come in many types: Computer grade, inverter grade, and pulse rated. Pulse Rated electrolytic capacitors include those used in camera flashes, and those I use on my multi stage coilgun. They differ from regular electrolytics by making use of thicker aluminium plates and stronger internal connections. The larger ones also have much bigger terminals, which are a direct indication of their intended high peak current. These capacitors are the perfect compromise between price, energy density and performance on a coilgun: They cost less than pulse capacitors and are lighter for the same energy storage, and their performance is only slightly below what a real pulse cap can achieve. Photo Flash capacitors also work well, though the smaller units require so many connections that a lot of resistance builds up on larger banks. Inverter grade capacitors are reasonable since they are made to operate at higher RMS currents and duty cycles than regular electrolytics; the computer grade capacitors. Even the worst electrolytic capacitors can be made to work in a coilgun, provided, as was said in the beginning of this tutorial, that they are of high enough voltage. 450V peak capacitors and 550V peak capacitors are the best ones because they do not require excessive series connection; because they have a very high ESR (Equivalent Series Resistance), electrolytic capacitors should not be placed in series for pulse applications because the ESR of the bank can very quickly become larger than the impedance of the load, and if that happens most of the energy of the discharge will be dissipated internally, damaging the capacitors. With pulse rated electrolytics it is possible to place some in series and thus obtain performance gains. My current systems operate at 900V, though even higher voltages would be desirable. The most efficient coilgun ever developed was fired at 3,5kV per stage.

nothing much to blog these few weeks. just some facts..
Wolf-Rayet stars (often referred to as WR stars) are evolved, massive stars (over 20 solar masses), and are losing their mass rapidly by means of a very strong stellar wind, with speeds up to 2000 km/s. While our own sun loses 10-14 of its own mass on a yearly basis, a Wolf-Rayet star loses 10-5 solar masses a year. These stars are also very hot: their temperature are in the range of 25,000 K to 50,000 K.
