    Is the higgs boson necessary for particles to exist.

    no doubt ok I know, that's why I make use of the word had and when they discovered. as to communicate my understanding that it had been discovered. I'm looking for a more scientific answer buddy, like what the higgs boson does exactly. I can get this information from wiki or textbooks, but I...

    Is the higgs boson necessary for particles to exist.

    why without the higgs boson, would particle physics be nonsense. why does this particle have such an important impact on particle physics. is this why it was called the god particle? its existence is unquestionably but no one had ever seen it. I bet when they discovered it the pa's were like...

    Problems with the Dreamliner battery

    from memory I remember the airbus had big problems with the power system. generators overheating in the engines caused fire. hmm. how do we know it wasn't sabotage.

    How to calculate a PMA's efficiency

    The charging amps must be more than the current draw in order to keep the batteries charged? This seems complicated as the output won't be constant.

    How to calculate a PMA's efficiency

    What is the charging and discharging formula? Is it If the battery is say 22AH, if I charge it at 5A it would take 4.4 hours to charge. that's without a current draw.

    Advice on building very primitive phased array radar

    Of course ILS uses two radio frequencies instead of a phased antenna. but the same thing applies as the plane will use two antenna tuned to both frequencies to plot its position. You want to read phase difference in one frequency. Which won’t be that good.

    Advice on building very primitive phased array radar

    My understanding is you want to detect the velocity and rough direction of an object using a phased antenna. Doing this will also give you a rough position like a ground to air ILS. Using two antenna will give you x and y space telemetry, Z of course would be the planes altimeter. I still say a...

    Advice on building very primitive phased array radar

    i would say 80Mhz with a prf of 30Khz

    Advice on building very primitive phased array radar

    You have a transmit frequency which you have established is 2.4 GHz. The prf is separate to the transmit frequency. The prf is how many times you pulse the 2.4 ghz so if your prf is 30Khz that would be pulsing the 2.4 Ghz 30,000 times a second.

    How to calculate a PMA's efficiency

    i would like to know this too. build your own turbine? this doesn't seem hard at all.. lol

    Advice on building very primitive phased array radar

    you will need a very high prf to do short distances.
