近代發明家有幾少?

點解好多偉大發明都喺以前,近代少了好多?
答案係,因為電視嘅偉大發明,睇電視嘅時間用多咗,又因為電腦嘅普及化,資訊塞多咗去個腦,少咗時間去諗發明。
呢個世界真係有金樹銀花,我呢個喺澳洲見嘅。

而電力嘅應用,都規範咗我哋嘅思維,唔知道有一次我同朋友講Linux真係好好用,佢答我:咁好用點解又唔見咁多人用?

從來都係D人話魚翅蛋白質好高,但係唔會話D雞蛋嘅蛋白質好高,係因為魚翅利潤高,所以花好多錢落廣告,你唔會為$2蚊嘅雞蛋賣下廣告後就可以賣出去$20蚊一隻吧。

其實喺發明電力應用最引起爭議係交流電同直流電,因為利益嘅鬥爭(科學家發明只有計第一,係冇第二㗎),發明電燈泡只係申請設計專利嘅利益鬥爭。

我認為尼古拉·特斯拉(Nikola Tesla)係一個偉大嘅科學家,偉大嘅意思係只發明而不計較專利嘅得失。
1919年,特斯拉寫道:「如果他完成馬達和發電機的改進工作,愛迪生將提供給他驚人的5萬美元(如計入通貨膨脹,相當於今天(2006年)的一百萬美 元)」。特斯拉說他的工作持續了將近一年,幾乎將整個發電機重新設計了,使愛迪生公司從中獲得巨大的利潤和新的專利所有權。當特斯拉向愛迪生索取5萬美元 時,愛迪生回答他:「特斯拉,你不懂我們美國人的幽默」,就此違背了自己的諾言。這筆獎金的金額相當於公司創始資本,而以特斯拉當時每周18美元的薪水,他需要工作53年才能賺到。當特斯拉要求加薪至每周25美元遭到拒絕後辭職。

The Tesla coil is one of Nikola Tesla's most famous inventions. It is essentially a high-frequency air-core transformer. It takes the output from a 120vAC to several kilovolt transformer & driver circuit and steps it up to an extremely high voltage. Voltages can get to be well above 1,000,000 volts and are discharged in the form of electrical arcs. Tesla himself got arcs up to 100,000,000 volts, but I don't think that has been duplicated by anybody else. Tesla coils are unique in the fact that they create extremely powerful electrical fields. Large coils have been known to wirelessly light up florescent lights up to 50 feet away, and because of the fact that it is an electric field that goes directly into the light and doesn't use the electrodes, even burned-out florescent lights will glow.

如你看發明家列表,不難發現其實近代嘅科技進步都係不斷改良先前嘅設計。我哋用緊既PC板設計都有30年啦。

196x年其實就有時光旅遊,你認為外星人存在嗎?我確信。
