Supermoon

The November 14, 2016 supermoon was 356,511 kilometres (221,526 mi) away^[1] from the center of Earth. It's size as seen with human eye is about 1.83cm. The last time the full moon approached so close to Earth was January 26, 1948, and it won't be closer until November 25, 2034 when it'll be 221,485 miles from the center of Earth.^[2]

A supermoon is the coincidence of a full moon or a New moon with the closest approach the Moon makes to the Earth on its elliptical orbit, resulting in the largest apparent size of the lunar disk as seen from Earth.^[3] The technical name is the perigee-syzygy of the Earth-Moon-Sun system ^[a]. The term "supermoon" is not astronomical, but originated in modern astrology.^[4] The association of the Moon with both oceanic and crustal tides has led to claims that the supermoon phenomenon may be associated with increased risk of events such as earthquakes and volcanic eruptions, but this is not true.^[5]

The opposite phenomenon, an apogee-syzygy, has been called a micromoon,^[6] though this term is not as widespread as supermoon.

Occasionally, a supermoon coincides with a total lunar eclipse. The most recent occurrence of this was in September 2015, while the next time will be in October 2033.^[7]

The most recent supermoon will occur on November 14, 2016, the closest to Earth since January 26, 1948, and while the next one like this will be until November 25, 2034.^[8] The closest supermoon of the century will occur on December 6, 2052.

“WhatsApp - End-to-End Encryption”

Why should we use WhatsApp???

We all want privacy and don’t want anyone else to hear our private conversations. But do you know, when you chat online, your messages can be read by third person very easily. Nowadays, several government and hackers are trying to get to your private life.

Normally, whatever msg you sent from your phone, it first goes to chat server (with very basic encryption) and then to the receiver’s phone. There’s no security attached. Anyone with the good hacking skills can hack your msgs from chat server.

--------------------------------------------------------------------------------

Suppose, this happens : You proposed a girl or texted your girlfriend through chat and on chat servers some hacker (her ex) changes your msg. You are ruined then.



--------------------------------------------------------------------------------

How WhatsApp is helpful??

Recently, WhatsApp introduced its End-to-End Encryption. This is basically :
1.Whatever msgs you sent from your phone, first it gets encrypted.
2.Then it is sent to WhatsApp servers. Here also, it is encrypted. (Even WhatsApp people can’t read it)
3.It reaches your Girlfriend (or receiver) and then with the you unique code (end-to-end encryption code) at her phone, it is decrypted. The she reads the msgs.

--------------------------------------------------------------------------------

Something about End-to-End Encryption :
1.It is a QR code or combination of 60 numbers.
2.It is unique for every chat room.
3.Now think, with the population of 1 billion (1,000,000,000) WhatsApp users, (Suppose) Each one having their atleast “1 billion” chat rooms. Still, they will be able to secure our msgs. With this end-to- end encryption, they are able to secure every chat rooms and each of your msgs.

(Do the MATH!!!)

Math -:

Here with the 60 numbers of end-to-end encryption - 10^60 (10 raised to power 60) unique numbers can be generated.

Now 1 billion (10^9) users having 1 billion (10^9) chat rooms EACH, so…..

Total, we need = 10^18 unique numbers for chat rooms.

WhatsApp can easily provide it.

See the beauty!!!



--------------------------------------------------------------------------------

(Important ) Remember : Before you start using any chat service, just check, how secure they are/(how secure it is)

Always check before using. Your privacy is really important.

End Of Chaturmasya Vrat; On Uthwasa Dwadashi, the Chaturmas Vrat ends. Devotees break their Ekadashi fast on this day and observe Vishnu Pujan and Tulasi Pujan. This is also the day when Lord Vishnu married Tulasi.

Tulasi Damodara Vivaha: This day also signifies the eternal marriage of Lord Vishnu and Tulasi. According to the Hindu belief, tulasi is regarded as Goddess Lakshmi. When tulasi plant was evolved into the Ksheer Sagar, the 'Samudra Manthan' was performed by the Gods and Demons. Tulasi appeared again from the ocean of milk and Lord Vishnu married her on this day.
