Atom Bomb

ویسے تو کہا جاتا ہے کہ ایٹم بم البرٹ آئنسٹائن کی ایجاد ہے
ایسا نہیں ہے کیونکہ ایٹم بم کے پیچھے نظریہ توآئنسٹائن کا ہی ہے
لیکن
ایٹم بم بنانے کے لیے ایک ٹیم بنائی گئی تھی جس میں بہت سے
لوگ شامل تھے اور اس ٹیم کے سربراہ تھے
Julius Robert Oppenheimer
اس لیے انکو ہی ایٹم بم کا موجد تصور کیا جاتا ہے

one by one answer
1 The Dictaphone's earliest development occurred at the Volta Laboratory established by Alexander Graham Bell in Washington, D.C. in 1881. When the Laboratory's sound recording inventions were sufficiently developed, Bell and his associates created the Volta Graphophone Company, which later merged with the American Graphophone Company, which itself later evolved into Columbia Records.
2 In 1885, the American inventor Tolbert Lanston applied for a patent on a typesetting system that included the basic Monotype keyboard, but which produced a printing surface through a cold-stamping method. In 1890, he filed a subsequent patent, which covered the Monotype caster.
In 1897, the Lanston Monotype Corporation opened a branch in England, which later became an independent company.
3 The engine was developed by German inventor Rudolf Diesel in 1893.
4 James Clerk Maxwell showed mathematically that electromagnetic waves could propagate through free space. Heinrich Rudolf Hertz and many others demonstrated radio wave propagation on a laboratory scale.
Nikola Tesla experimentally demonstrated the transmission and radiation of radio frequency energy in 1892 and 1893 proposing that it might be used for the telecommunication of information.[2][3] The Tesla method was described in New York[4] in 1897.[5][6] In 1897, Tesla applied for two key United States radio patents, US 645576, first radio system patent, and US 649621.[7] Tesla also used sensitive electromagnetic receivers,[8][9][10] that were unlike the less responsive coherers later used by Marconi and other early experimenters.[dubious – discuss] Shortly thereafter, he began to develop wireless remote control devices.
In 1895, Marconi built a wireless system capable of transmitting signals at long distances (1.5 mi./ 2.4 km).[11] From Marconi's experiments, the phenomenon that transmission range is proportional to the square of antenna height is known as "Marconi's law".This formula represents a physical law that radio devices use.
5 Volta did not appreciate that the voltage was due to chemical reactions. He thought that his cells were an inexhaustible source of energy,[15] and that the associated corrosion effects at the electrodes were a mere nuisance, rather than an unavoidable consequence of their operation, as Michael Faraday showed in 1834.[16] According to Faraday, cations (positively charged ions) are attracted to the cathode,[17] and anions (negatively charged ions) are attracted to the anode.
6 German physicist Wilhelm Röntgen is usually credited as the discoverer of X-rays in 1895, because he was the first to systematically study them, though he is not the first to have observed their effects. He is also the one who gave them the name "X-rays", though many referred to these as "Röntgen rays" (and the associated X-ray radiograms as, "Röntgenograms") for several decades after their discovery and even to this day in some languages, including Röntgen's native German.
7 The important early researchers in X-rays were Ivan Pulyui, William Crookes, Johann Wilhelm Hittorf, Eugen Goldstein, Heinrich Hertz, Philipp Lenard, Hermann von Helmholtz, Thomas Edison, Charles Glover Barkla, Nikola Tesla, Max von Laue, and Wilhelm Conrad Röntgen.
German physicist Johann Hittorf (1824–1914), a co-inventor and early researcher of the Crookes tube, found when he placed unexposed photographic plates near the tube, that some of them were flawed by shadows, though he did not investigate this effect.[citation needed]
In 1877 Ukrainian-born Pulyui, a lecturer in experimental physics at the University of Vienna, constructed various designs of vacuum discharge tube to investigate their properties.
8 Edward Teller (Hungarian: Teller Ede; January 15, 1908 – September 9, 2003) was a Hungarian-born American theoretical physicist,[1][2][3] known colloquially as "the father of the hydrogen bomb",
