Who discovered pie
The great mathematician Aryabhata
discovered the theory of pi (π)
When the
people of Europe were learning mathematics, the great Indian mathematician
Aryabhatta was solving the complex puzzle of Pai. Aryabhata, who invented the
decimal system in mathematics and made the world aware of zero, also proposed
the theory of Pi.
Not only
this, he invented equations to solve complex mathematical problems easily,
which people all over the world still use. Let's know some interesting things
about pie.
1. What is Pie?
In geometry
the ratio of the length of the circumference of a circle to the length of the
diameter is called pi. The ratio in each circle is 3.141, but the whole number
after the decimal has not yet been estimated, so it is considered infinite.
Aryabhata has written in Sanskrit, rendering its theory.
चतुराधिकं शतमष्टगुणं द्वाषष्टिस्तथा सहस्त्राणाम्।
अयुतद्वयस्य विष्कम्भस्य आसन्नौ वृत्तपरिणाहः॥
अयुतद्वयस्य विष्कम्भस्य आसन्नौ वृत्तपरिणाहः॥
Add four to 100, multiply by eight and then add 62,000. The
diameter of a circle of 20,000 circumference can be determined by this rule.
That is, if
the diameter of a circle is 20,000, its circumference will be 62,232.
It is
noteworthy that despite accurate and correct calculations at four decimal
places, Aryabhata, who is inclined towards the truth, does not consider this
value pure. Rather believed to be adjacent.
2. Use of Pie
Pie is
mostly used in geometry. The tradition of writing marks in radian made it an
integral part of trigonometry. There is also a lot of use in estimation or
probability. Its biggest example is the Buffon's Needle problem. It is used in
almost every branch of mathematics. Also this number is used in science and
engineering.
3. Early History of Pie
It is
undisputed truth that Aryabhata was the proponent of Pai's theory. Despite
this, everyone, from Archimedes to Newton, had discovered about pie and put their
values in front of the world. Brahmagupta, another mathematician from India,
also took Pai's discovery to a new height. Those who built the Egyptian
pyramids are believed to have knowledge of the pie. However, no written
evidence is available.
4. Discover Archimedes
Archimedes
stated that the pie occurs between 223/71 and 22/7. Archimedes is often called
the designer of mechanical devices, but his contribution to the field of
mathematics is also matchless. Archimedes could use infinite series in the same
way as in modern inseparable calculations. He used his 'technique of technique
perfection' to find the approximate value of pi.

5. Pie Count

Numerous
examples of pie counts are found in the history of ancient India. On the basis
of calculations, various sizes and types of yajna-altars were made. Aryabhata
solved some difficult questions. For example, by adding the areas of two
right-angled squares, the number that will come is to make that area a
'right-angled equilateral square and change that shape into a circle equal to
its area. e.t.c.

Secret of Pie (π)
Definition pie (π)
Definition pie (π)
Secret of Pie The history of pie is thousands of
years old, we have been using human pie since ancient times. But do you know
what pie is! And what about π from stephin Hawking and Albert Einstein!
I know that
many people do not like mathematics, so believe me that in this video we will
only know the secrets of pie and will not use maths at all!
Actually,
this is the time when humans invented the first wheel! Humans have made the
wheel but it was not round! Because of this, when those people moved here and
there, there was a fear of spreading their luggage because the wheels were not
round!
Similarly,
time passes but they say! Neither any new thing is invented when we need it!
 |
| Secret of Pie (π) |
As the need
to talk to relatives located thousands of kilometers away, the telephone was
invented! Electricity was invented when you felt the need for light! Meaning
when we feel a problem or not, then a new idea is born in our mind to get rid
of that problem and becomes a new invention!
Similarly,
when the history of the wheel kept moving forward and the wheel turned round,
people knew that a wheel is completely round then! When the ratio of its
circumference and its diameter is a constant number and whether the circle is
small or large, but the value of this constant is always the same! And named
the constant number π which is
denoted by the letter on the 14th number in Greek language! Now people know
that there is always a constant in any round shape! But people still did not
know that constant ie value! And the interesting thing is that even today we do
not know the true value of pie and the super computer also gave up on losing
the value of pie!
And some
people have gone through their entire life only to find the value! Those people
have passed away, but the value of the pie has not yet come out! Now you must
be wondering why the value of the paper is so important and why its value is so
difficult to extract! This is easy, we have found the value of 22/4 in school!
By multiplying 22 by 4, the value of the pie will be out.
But let me
tell you among my friends that Bo who has read the value of his pie 22/4 is
wrong! And read your wrong!
Actually pie
is an irrational number and its value can never be doubled! You will be
surprised to know that without pie, we cannot do any mission in space! Nor
could I ever make an airplane! Well let's know! What is the 22/4 that I have
read till now? If the circumference of a round shape is 22 units, then its
diameter should be 4 units to make it the perfect circle. And the ratio of
Paridhi and Diameter is the constant number called π!
Well now let
us know why what we studied in school is wrong! Actually, when we divide 22
from 4, the value will be 3. 14285714286 but the real value of the pie is
something! 3 .1415926535897….
 |
| Secret of Pie (π) |
And you will
be surprised to know that the supercomputer of modern doors got 5 trillion
values after the decimal of the pie, and beyond that the value of the super
computer pie was lost in the calculation! Unique secret of pie by super
computer you don't know! Do you know that Pipai day is also celebrated! And
that is why it is celebrated only on March 14, so the answer lies in the value
of the pie itself! 3 .14 And you will be surprised to know that a fix time is
fixed for celebrating pi day on 14 March too! And that is 1 .59 pm Now why is
pie day celebrated at this time! So for this we have to increase the value of π
by 3 .14159 Secret of Pi.
Now what I
am going to tell you in the future is either a coincidence or a miracle of
nature!
The great
scientist Albert Einstein was born on the 14th of March in the world of
physics! And now to tell another coincidence, on 14 March, the great scientist Stephen Hawking died!

| 互联网 |
互联网
定义-互联网是什么意思？
互联网是一个全球连接的网络系统，使用TCP / IP通过各种类型的媒体传输数据。 互联网是由向导，无线和光纤技术连接的全球交流网络，包括私人，公共，企业，学术和政府网络。
互联网和万维网这两个术语经常互换使用，但是它们并不完全相同。 互联网是指包括硬件和基础设施在内的全球通信系统，而网络是通过互联网进行通信的服务之一。
技术百科解释了互联网
随着计算的进步，对等（P2P）通信逐渐交付和增强。 自1990年代以来，互联网极大地影响了网络并将其升级为全球标准。 数十亿互联网用户依赖多种应用程序和网络技术，包括：
互联网起源于美国政府，美国政府于1960年代开始建立称为ARPANET的计算机网络。 1985年，美国国家科学基金会（NSF）委托开发了一个名为NSFNET的大学网络骨干。
互联网协议（IP）：互联网的主要组成部分和通讯主干。 由于Internet由硬件和软件层组成，因此IP通信标准用于解决方案并标识唯一的连接设备。 用于通信的突出IP版本包括Internet协议版本4（IPv4）和Internet协议版本6（IPv6）。
通讯：互联网是世界上最具成本效益的通讯方式，可以立即使用以下服务：
· 电子邮件
· 支持Web的音频/视频会议服务
· 在线电影和游戏
· 数据传输/文件共享，通常通过文件传输协议（FTP）
· 即时通讯
· 互联网论坛
· 社交网络
· 网上购物
· 金融服务
该系统在1995年被商业互联网服务提供商运营的新网络所取代。大约在这个时候，互联网被大规模地引入了公众。

历史
分组交换（一种基本的互联网技术）的研究始于1960年代初期的Paul Baran [14]，以及诸如Donald Davies的NPL网络，ARPANET，Merit网络，CYCLADES和NPL网络之类的分组交换网络。电信是在1960年代末和1970年代初开发的。[15] ARPANET项目促成了互联网络协议的开发，通过该协议，可以将多个单独的网络合并成一个网络网络。[16]
ARPANET的开发始于两个网络节点，它们之间是由伦纳德·克莱因洛克（Leonard Kleinrock）指导的加州大学洛杉矶分校（UCLA）亨利·萨缪里工程与应用科学学院的网络测量中心与SRI国际（SRI）的NLS系统互连的。道格拉斯·恩格尔巴特（Douglas Engelbart），1969年10月29日在加利福尼亚州门洛帕克。[17]第三个站点是加利福尼亚大学圣巴巴拉分校的卡勒弗里德交互式数学中心，其次是犹他大学图形系。到1971年年底，有15个站点与年轻的ARPANET相连，这是未来增长的早期迹象。[18] [19] 1972年的电影《计算机网络：资源共享的先驱》记录了这些早期的年代。
ARPANET早期的国际合作很少见。欧洲开发人员关注开发X.25网络。[20]值得注意的例外是1973年6月的挪威地震台阵（NORSAR），随后是1973年的瑞典，与塔努姆地球站和英国的彼得·T·柯尔斯坦的研究小组建立了卫星链接，最初是在伦敦大学计算机科学研究所后来在伦敦大学学院。[21] [22] [23] 1974年，RFC 675使用互联网一词作为互联网络的简写，[11]之后，RFC重复了这一使用。[24] 1981年，美国国家科学基金会（NSF）资助了计算机科学网络（CSNET），扩大了对ARPANET的访问。 1982年，Internet协议套件（TCP / IP）进行了标准化，从而使互连网络在全球范围内得到了普及。 TCP / IP网络访问在1986年再次扩大，当时美国国家科学基金会网络（NSFNet）为研究人员提供了对美国超级计算机站点的访问，首先是56 kbit / s的速度，然后是1.5 Mbit / s和45 Mbit / s的速度。 。[25]商业互联网服务提供商（ISP）出现在1980年代末和1990年代初。 ARPANET于1990年退役。
互联网在1980年代中期至后期[26] [27]在欧洲和澳大利亚迅速扩展，并在1980年代末期和1990年代初在亚洲迅速发展。[28] 1988年12月，普林斯顿大学与瑞典斯德哥尔摩之间的低速卫星中继站开始了NSFNET与欧洲网络之间跨大西洋专用通信的开始。[29]尽管其他网络协议（例如UUCP）在此之前就已经达到了全球范围，但这标志着Internet作为洲际网络的开始。
半导体技术和光网络的稳步发展为商业参与其核心网络的扩展以及向公众提供服务创造了新的经济机会。 1989年中，MCI Mail和Compuserve建立了与Internet的连接，向50万Internet用户提供了电子邮件和公共访问产品。[30]仅仅几个月之后，即1990年1月1日，PSInet推出了备用Internet主干用于商业用途；后来成为商业互联网核心的网络之一。 1990年3月，康奈尔大学与欧洲核子研究组织（CERN）之间建立了NSFNET与欧洲之间的第一条高速T1（1.5 Mbit / s）链路，与卫星相比，通信能力更强。[31]六个月后，蒂姆·伯纳斯·李（Tim Berners-Lee）将开始编写WorldWideWeb，这是在游说CERN管理层两年后的第一个Web浏览器。到1990年圣诞节，Berners-Lee已经建立了运行Web所需的所有工具：超文本传输协议（HTTP）0.9，[32]超文本标记语言（HTML），第一个Web浏览器（也是HTML编辑器和可以访问Usenet新闻组和FTP文件），第一个HTTP服务器软件（后来称为CERN httpd），第一个Web服务器[33]和描述项目本身的第一个网页。 1991年，商业互联网交换所成立，允许PSInet与其他商业网络CERFnet和Alternet通信。
1994年10月，斯坦福联邦信用联盟是第一家为其所有成员提供在线互联网银行服务的金融机构。[34] 1996年，OP金融集团（也是合作银行）成为全球第二家网上银行，欧洲第一家银行。[35]到1995年，当NSFNet退役时，互联网在美国已完全商业化，从而取消了使用互联网承载商业流量的最后限制。[36]
随着技术的进步和商业机会的不断增长，互联网流量开始出现与半导体电路规模缩放类似的特征（摩尔定律就是例证），每18个月翻一番。半导体技术，激光波系统和噪声性能的进步推动了这种增长形式化为埃德霍尔姆定律。[39]

| 互联网 |
自1995年以来，互联网已极大地影响了文化和商业，包括电子邮件，即时消息，电话（互联网协议语音或VoIP语音），双向双向视频通话和万维网[40]的近乎即时的通信的兴起。以及其论坛，博客，社交网络和在线购物网站。通过以1 Gbit / s，10 Gbit / s或更高速度运行的光纤网络，越来越多的数据以越来越高的速度传输。在越来越多的在线信息和知识，商业，娱乐和社交网络的推动下，互联网继续增长。[41]在1990年代后期，据估计公共Internet上的流量每年以100％的速度增长，而Internet用户数量的年均增长被认为在20％至50％之间。[42]这种增长通常归因于缺乏中央管理，这导致网络的有机增长，以及Internet协议的非专有性质，这鼓励了供应商的互操作性，并阻止了任何一家公司对网络施加过多的控制权。[43]截至2011年3月31日，互联网用户总数估计为20.95亿（占世界人口的30.2％）。[44]据估计，在1993年，互联网仅承载通过双向电信传输的信息的1％，到2000年，这一数字已增长到51％，到2007年，超过97％的所有电信信息都是通过互联网进行的。[
