Everything you need to know about eSIM

History of Sim Cards

1991:

There used to be Full-Size Sim Cards created in 1991 by the German company Giesecke and Devrient, the full-size SIM was about the same size as today’s Credit or Debit Cards.

1996:

Mini-SIM Cards came into existence in 1996 and were most commonly recognized. It was known as the standard SIM that fits all types of phones and stores all users’ information. Mini-SIM Cards came to an end completely after the innovation of Smartphones later after 2010. The Size of Standard-SIM or Mini-SIM is 25mm x 15mm.

2003

In 2003, Apple introduced the micro-SIM. It was essentially marketed as a more compact version of the previous mini-SIM. By 2010, the micro-SIM had become the standard SIM size for smartphones. The Size of Micro-SIM is 15mm x 12mm.

2012:

Nano-SIM was introduced in 2012, which is quite a smaller and thinner version of the micro-SIM. Even in 2021, this is still considered to be the standard SIM card size. The Size of Nano-SIM is 12.3mm x 8.8mm.

What is an eSIM? The Future is here:

eSIM refers to an electronic or embedded SIM that is used instead of physical SIM cards to make life easier.. It is a small chip that works similarly to the NFC chip used for payment technology like Google Pay or Samsung Pay and Apple Pay.

The Google Pixel 2 was the first smartphone to support and promote eSIM technology with an in-built application for managing your eSIM. Further, for iOS, iPhone XS offered eSIM technology with the support of Physical SIM cards too.

With that being said, the eSIM technology is the future, and it will take time to dominate the market.

How eSIM will benefit you?

It helps to make devices or smartphones compact and tiny so that your other components like batteries, Chipsets get more space to fit in your smartphone.
Moving from Physical to Electronic is the main motive and concept of the Internet World, and this eSIM technology will definitely be the innovation for the Modern Era.
No more Physical contact/damage with/to your SIM Cards.
It is Easier to Switch between the networks
There’s no chance of losing your eSIM

Disadvantages of eSIM:

It is not the cheapest option available.
There are very few eSIM capable devices in the market.
Switching phones is complicated.
Highly possibility of getting Hacked.

NASA to study secrets of universe with smaller missions

NASA has selected the deployment of four astrophysics for the development of cognitive development in a new system called Pioneers.

“The chief investigators of these theoretical studies brought new ideas, out of the box thinking about the problem of how large astrophysics experiments could be done on a small budget,” said Thomas H. Zurbuchen, co-ordinator of NASA’s Science Mission Directorate. “

Here are four concepts were chosen for further study:

Aspera is a SmallSat that will study the evolution of galaxies. The intergalactic medium is a major component of the universe but is measured. Aspera will close this gap, Principal Investigator Carlos Vargas at the University of Arizona.

Pandora is a SmallSat that will study 20 stars and their 39 exoplanets in visible and infrared light. The purpose is to unravel signals from the star and planetary atmospheres. Understanding how changes in starlight affect the measurement of extrasolar planets is an open question in finding habitable planets across the solar system. The main researcher is Elisa Quintana of the NASA Goddard Space Flight Center.

StarBurst is a SmallSat that detects high-energy gamma rays from events such as the coalescence of dense stellar debris called neutron stars. This provides valuable insights into such events, which are also detected by gravitational waves from observatories on Earth.

PUEO is a balloon mission designed to launch from Antarctica, which detects signals from ultra-high energy neutrinos. Highest energy astrophysical processes such as black hole creation and neutron star merger. PUEO will be the most sensitive investigation of the cosmic ultrahigh-energy neutrinos ever conducted. The Pioneer Program offers innovative experimentation to early and mid-career researchers, and for the first time in space, Or allow you to lead suborbital scientific research.

“Designed to attract young professionals, this program has received 24 great ideas from a diverse cohort. Director of NASA’s Astrophysics Department at NASA headquarters in Washington. The program itself is an experiment for NASA, and this institution has never requested a proposal for this kind of astrophysics experiment at low-cost limits with these strict constraints. Some concepts, with further research, may require a larger budget. In other words, flights under the Pioneer Program will not be finally approved.

Human Brain

உலகத்திலேயே மிகவும் சக்திவாய்ந்தது மனிதனின் மூளை மட்டுமே வேறு எந்த உயிரினத்திற்கும் அவ்வளவு திறன் இல்லை. (உ.தா) மொத்த உலகத்தின் சுற்றளவே 45.000 கிலோ மீட்டா் தான் ஆனால் மனித மூளையின் நரம்புகளை ஒன்றினைத்தால் மொத்தம் 1 லட்சம் கிலோ மீட்டா் அளவு இருக்குமாம். நம் உடலின் மொத்த எடையில் 2% அளவு மூளைக்கு செல்கிறது. அந்த 2% அளவு கொண்ட மூளை நம் உடலில் சராசரியாக 20% சக்திகளை எடுத்துக் கொள்ளுமாம், இளைஞா்கள் என்றால் 50% மும் குழந்தைகள் என்றால் 60% மும் எடுத்துக்கொள்ளுமாம் அந்த அளவிற்கு மனித மூளையில் திறன் ஆற்றல் செயல்படுமாம். நம் உறங்கும் போது கூட மூளை உறங்குவதில்லையாம்.

பெண்களின் மூளையை விட ஆண்களின் மூளை 10% கூடுதல் அளவுடையது. இந்த அளவிற்கு திறன் கொண்ட மூளைக்கு நாம் செய்ய கூடாதவை என்னவென்றால்

காலை உணவை தவிர்க்க கூடாது. கட்டாயம் உட்கொள்ள வேண்டும்.
தூக்கும் நேரத்தில் முழுவதும் முகங்களை மூடிக்கொண்டு உறங்க கூடாது.
உடல் நிலை சரியில்லாத நேரங்களில் மூளைக்கு அதிகம் வேலை தர கூடாது. ஓய்வு தர வேண்டும்.
