1、爱迪生发明的留声机
爱迪生是美国著名的科学家和发明家,因为他有电灯、留声机、电影和蓄电池等一千多种发明成果,所以人们称他为“发明大王”、“魔术师”。
爱迪生最大的功绩是发明了电灯,然而在他的发明创造中,最引起当时社会震惊的,莫过于留声机了。在1877年秋天,爱迪生发明的留声机轰动了整个纽约,各家报馆的新闻记者。
像潮水般地涌来报道这一特大新闻。这一发明一经传出,激起当时社会急速而巨大的狂热达数月之久,铁路特开专车前去参观,许多人开始不相信这个发明。
疑心他是先在里面藏了个什么会说话的东西骗人的,有个教堂的主教用最高速度对着收音盘背诵《圣经》中的一串专门名词。
当这些名词一字不漏的从机器中重复出来时,人们才相信这东西确实不是虚假的,并且齐声称奇,报纸把留声机称之为19世纪的奇迹。
2、电话的发明
贝尔,就是发明电话的人。他1847年生于英国,年轻时跟父亲从事聋哑人的教学工作,曾想制造一种让聋哑人用眼睛看到声音的机器。
1873年,成为美国波士顿大学教授的贝尔,开始研究在同一线路上传送许多电报的装置——多工电报,并萌发了利用电流把人的说话声传向远方的念头。
使远隔千山万水的人能如同应对面的交谈。于是,贝尔开始了电话的研究。那是1875年6月2日,贝尔和他的助手华生分别在两个房间里试验多工电报机,一个偶然发生的事故启发了贝尔。
华生房间里的电报机上有一个弹簧粘到磁铁上了,华生拉开弹簧时,弹簧发生了振动。与此同时,贝尔惊奇地发现自己房间里电报机上的弹簧颤动起来,还发出了声音。
是电流把振动从一个房间传到另一个房间。贝尔的思路顿时大开,他由此想到:如果人对着一块铁片说话,声音将引起铁片振动;若在铁片后面放上一块电磁铁的话。
铁片的振动势必在电磁铁线圈中产生时大时小的电流。这个波动电流沿电线传向远处,远处的类似装置上不就会发生同样的振动,发出同样的声音吗?
这样声音就沿电线传到远方去了。这不就是梦寐以求的电话吗!贝尔和华生按新的设想制成了电话机。在一次实验中,一滴硫酸溅到贝尔的腿上。
疼得他直叫喊:“华生先生,我需要你,请到我那里来!”这句话由电话机经电线传到华生的耳朵里,电话成功了!1876年3月7日,贝尔成为电话发明的专利人。
3、罗兰·希尔发明邮票的故事
人类社会的发展,决定了人类单靠个人的力量是无法在地球上长期存活下去的。人类需要帮忙,人类需要交流,信息传递成了人类生存必需的基本活动之一。
最初是打手势,之后发明了语言,用马拉松式的长跑传递口信。再以后发明了文字,开始书信传递,于是有了古代邮驿。当时的邮资是按邮件运递路程和信件纸张数量逐件计算的。
即“递进邮资制”,收费的标准也很高。如果遇到江河泛滥、桥梁坍塌,信件就得多走几百公里。总计下来,邮资高得吓人。如此昂贵的邮资,是平民百姓望而生畏。
他们把寄信看成一件奢侈的事情。19世纪30年代是改革的黄金年代,改革造就了一代英雄。罗兰·希尔发明了世界上第一枚邮票,在世界邮政史上树起了一座划时代的里程碑。
罗兰·希尔经过多年的调查主张大幅度降低邮费,实行邮件不分远近、一律收费1便士的均一邮资。他还提出使用“印刷精美的邮政用品”来预先支付邮资。这种纸的大小与邮资图样大小相仿。
背面涂上一层薄胶,人们只要沾湿背胶就能够将其贴在信件上,这就是罗兰·希尔关于邮票的最初创意。为此,罗兰·希尔上书政府,提出了自己的改革推荐。
1839年8月17日,维多利亚女王批准了这个议案,决定英国自1840年1月10日起实行1便士均一邮资法。罗兰·希尔也被女王任命负责邮政改革工作。为了把创意中的1便士邮票变成现实。
罗兰·希尔要求就应使用具有防伪性能并能在公众中取得信誉的图案作为邮票的图案。于是采用了威廉·怀恩创作的维多利亚女王的侧面头像,这样既显示了发行邮票的权威性。
又透过邮票宣传了英国,宣传了女王。邮票采用黑色油墨印刷,1840年4月15日,最后印出了世界上第一批邮票——黑便士邮票。
4、张衡发明地动仪的故事
中国的历史上,除了文人雅士、帝王将相,也有很多的科学家,张衡就是其中很著名的一个。张衡一生做了很多的事情,但是,他最有名的发明就是“地动仪”了。
那个时期,经常发生地震。有时候一年好几次。发生一次大地震,就会给老百姓和国家带来很多的伤害。当时的皇上和老百姓都把地震看作是不吉利的征兆,认为是鬼神造成的。
张衡却不信神邪,他对记录下来的地震现象经过细心的考察和试验,发明了一个能测出地震的仪器,叫做“地动仪”。地动仪是用青铜制造的,形状像一个酒坛,四围铸着八条龙。
龙头伸向八个方向。每条龙的嘴里含着一颗小铜球,龙头下面,蹲了一只张着大嘴的蛤蟆。哪个方向发生了地震,朝着那个方向的龙嘴就会自动张开来,把铜球吐出。
铜球掉在蛤蟆的嘴里,发出响亮的声音,就告诉人们那边发生地震啦。公元138年2月的一天,地动仪正对着西方的龙嘴突然张开来,吐出了铜球,这是报告西部发生了地震呀。
但是,那天洛阳一点地震的迹象也没有,更没有听说附近有什么发生了地震。于是,朝庭上下都议论纷纷,说张衡的地动仪是骗人的玩意儿。
过了没几天,有人骑着快马来向朝廷报告,离洛阳一千多里的金城、陇西一带发生了大地震,连山都有崩塌下来的。大伙儿这才真正的信服了。
5、避雷针的发明
1752年,46岁的美国科学家富兰克林用绸子做了一个风筝,并在一个风雨交加的天气里用麻线把风筝放上天空。麻线下端系了一把金属钥匙,当雨水把麻线浇湿以后就变成了导电体。
这时,他把手靠近钥匙,突然看到电火花在钥匙和手指之间跳过,同时,手指感到一阵刺痛。这个实验证明了天空中打雷实际上就是一种大规模的放电现象。
由此,使富兰克林想到,如果在高大的建筑物上装一根金属导线,导线下端接地,根据尖端放电的原理,就可避免建筑物遭到雷击的危险。这就导致了避雷针的发明。
由于避雷针的发明,人类生活的世界就多了几分安全。关于避雷针的发明,似乎是一个偶然事件。一个巧合提醒了一位伟人突发奇想,导致了发明和创造。
1, what edison invents is phonographic
Edison is the United States' famous scientist and inventor, because he has the positive result of more than 1000 kinds of inventions such as electric lamp, phonographic, film and accumulator, so people call him " invention king " , " charmer " .
The contribution with the largest edison was to invent electric light, it is however in his creation, cause what the society astonishs at that time most, nothing is more... than is phonographic. Summer 1877, the phonographic sensation that edison invents whole new York, the journalist of each newspaper office.
Emerge to report this one especially big news like the ground like tidewater. Once this one invention comes out, arouse at that time social quickness and what tremendous enthusiasm amounts to a few months is long, before railroad opens special especially, go looking around, a lot of people begin not to believe this invention.
Suspect the thing that what hid to be able to talk inside preexistence deceives people him, a church bishop uses top speed to reception of a radio dish recital " Bible " a medium string of technical term.
When these nouns one word does not repeat of leakage from inside the machine when coming out, people just believes this thing is not false really, and in chorus says surprise, newspaper phonographic the is 19 centuries miracle that say.
2, the invention of the phone
Bell, invent the person of the phone namely. He was born at England 1847, young when the education that pursues a deaf-mute with father works, ever wanted to make a kind let a deaf-mute see audio machine with the eye.
1873, become the Bell that American Bostonian university teachs, begin to consider to convey on same line a lot of telegraphic device -- multitask cable, and bud the idea that uses electric current to transmit talking sound of the person to distance.
Make remoteness 1000 hill the person of 10 thousand water can is opposite as answering of the face chat. Then, bell began the research of the phone. That was on June 2, 1875, bell with his assistant China is born to be respectively in two rooms experiment multitask telegraph, an occurrent accident inspired Bell.
China there is a bedspring to be stuck to magnet on the telegraph in unripe room, china unripe when pulling open bedspring, bedspring produced vibration. Meanwhile, the bedspring that Bell discovers the telegraph in him room amazedly to go up is vibratile rise, still gave out sound.
It is electric current transmits vibration to another room from a room. Bell's train of thought leaves greatly immediately, he thinks of from this: If person to an iron piece talk, sound will cause iron piece oscillatory; If be in iron piece from the back if putting an electro-magnet.
Iron piece the electricity that oscillatory certainly will produces size in electro-magnet coil. Electrical wiring of edge of this fluctuant electric current is passed to far, same vibration can not produce on the similar device of far, give out same sound?
Such sound travel distance with respect to edge electrical wiring. Is this the phone that long for day and night! Shellfish Er He Huasheng made telephone by new tentative plan. In experiment, vitriolic on the leg that splashs Bell.
Ache so that he cries continuously: "China unripe gentleman, I need you, come there me please! " this word is passed by phone classics electrical wiring China in unripe ear, the phone succeeded! On March 7, 1876, bei Ercheng is the patent person that the phone invents.
3, collect the story that Lan Hill invents a stamp
The development of human society, the power that decided human sheet relies on an individual cannot retain subsist for a long time on the earth. The mankind needs to help, the mankind needs to communicate, information delivered the mankind to live one of indispensible primary activities.
It is pantomime at first, the language was invented later, the long-distance race that uses marathon formula delivers oral message. Invented a character later again, begin epistolary deliver, had ancient time to mail post then. The postage at that time is to press mail carry to give distance and correspondence paper amount to chase a calculative.
Namely " go forward one by one postage is made " , the level that collect fees is very high also. If encounter Jiang He cave in of flush, bridge, letters has to go hundreds of kilometers more. Add up to comes down, postage is gotten high fearsome. So costly postage, it is be terrified by the sight of sth or sb of civilian common people.
They send a letter to regard as a luxury business. 19 centuries the gold time that 30 time are reform, reform brought up generation hero. Collect Lan Hill invented the first stamp, in the world postal Shi Shangshu removed an epoch-making milepost.
Collect Lan Hill reduces postage substantially through old investigation position, execute mail to be not divided far and near, uniform collect fees the even postage of 1 penny. He still puts forward to use " presswork exquisite postal articles for use " will pay postage beforehand. The size of this kind of paper and similar of postage design size.
A thin glue, people wants bedew to carry glue on the back to be able to stick its on correspondence only, this is collect Lan Hill the original originality about the stamp. For this, collect Lan Hill government of submit a written statement to a higher authority, the reform that formulated oneself is recommended.
On August 17, 1839, victoria queen approved this second reading, decision England executes 1 penny since January 10, 1840 even postage law. Collect Lan Hill also is appointed to be in charge of postal reform working by queen. To turn the 1 penny stamp in originality into reality.
Collect the design that Lan Hill asks to should use the design that have the property that prevent bogus and can gain reputation in the public to serve as a stamp. The head of Victoria queenly flank that used Williams · Huai En to create then, showed the authority that issues a stamp already so.
Publicized England through the stamp again, publicized queen. The stamp uses black printing ink to presswork, on April 15, 1840, imprint finally gave the first batch of stamps -- black penny stamp.
4, the story that Zhang Heng invents quake appearance
On Chinese history, besides photograph of bookman refined scholar, monarch general, also have a lot of scientists, zhang Heng is among them a very famous. Zhang Heng did a lot of businesses all one's life, but, his famousest invention is " quake appearance " .
That period, often produce an earthquake. Occasionally a year many times. Produce earth shake, can bring a lot of harm to common people and country. The emperor at that time and common people regard the earthquake is ominous sign, consider as ghosts and gods to cause.
Zhang Heng is godless however unhealthy environmental influences that cause disease, the seismic phenomenon course that he comes down to the record makes an on-the-spot investigation attentively and experiment, invented an instrument that can measure an earthquake, be called " quake appearance " . Quake instrument is made with bronze, appearance resembles world of a wine, all around casting is worn 8 dragon.
Bibcock is extended to 8 direction. There is ball of a small copper in the mouth of every dragon, below bibcock, crouched a toad of piece of move big mouth. Wh which direction produced an earthquake, forward the dragon mouth of that direction can be stretched automatically come, spit cupreous ball.
Cupreous ball drops the mouth in toad in, give out canorous sound, tell people shake of virgin soil of the hair there. The Christian era a day of 138 years Feburary, quake appearance is being stretched suddenly to dragon mouth of the west come, spat cupreous ball, this is a report western produced an earthquake.
But, the evidence of a bit earthquake also did not have Luoyang that day, do not have more hear around what produced an earthquake. Then, court law court comments up and down in succession, the quake appearance that says Zhang Heng is the plaything that deceive people.
Passed to do not have a few days, somebody is riding post-horse to report, from Luoyang one belt produced more than 1000 lis Jin Cheng, Gansu on the west earth shake, lian Shan has collapse to come down. We all the conviction with this real talent.
5, the invention of lightning rod
1752, american scientist rich Lan Kelin of 46 years old made a kite with silk fabric, use twine to put kite in a wet and windy weather God is empty. Twine lower end fastened key of a metal, irrigate twine when rainwater wet became electric system later.
At this moment, his handle stands by the key, see electric spark suddenly be jumped over between the key and finger, in the meantime, finger feels one is prickled. This experiment proved to thunder in the sky is a kind of large-scale discharge phenomenon actually.
From this, richen Lan Kelin thinks of, if make up in tall building lead of a metal, lead leaves termination ground, according to the principle of point discharge, with respect to the risk that can avoid a building to suffer be struck by lightning. This brought about the invention of lightning rod.
As a result of the invention of lightning rod, the world that the mankind lives is much a few minutes of safety. About the invention of lightning rod, it is a haphazard it seems that. A coincidence reminded a great person to break out crank, brought about invention and creation.
