Map of Computer Science

The field of computer science summarised. Learn more at this video's sponsor

Computer science is the subject that studies what computers can do and investigates the best ways you can solve the problems of the world with them. It is a huge field overlapping pure mathematics, engineering and many other scientific disciplines. In this video I summarise as much of the subject as I can and show how the areas are related to each other.

A couple of notes on this video:
1. Some people have commented that I should have included computer security alongside hacking, and I completely agree, that was an oversight on my part. Apologies to all the computer security professionals, and thanks for all the hard work!
2. I also failed to mention interpreters alongside compilers in the complier section. Again, I’m kicking myself because of course this is an important concept for people to hear about. Also the layers of languages being compiled to other languages is overly convoluted, in practice it is more simple than this. I guess I should have picked one simple example.
3. NP-complete problems are possible to solve, they just become very difficult to solve very quickly as they get bigger. When I said NP-complete and then impossible to solve, I meant that the large NP-complete problems that industry is interested in solving were thought to be practically impossible to solve.

Cell Membrane in Hindi Part 1/2 | plasma membrane structure and function

In this lecture we discuss about the Cell Membrane / Plasma membrane. plasma membrane structure function and types of lipid from which it formed. Cell Membrane in Hindi Part 1/2 | Plasma Membrane | cell biology lecture in hindi | vinay rajput. Surrounding of each of our cells is a membrane called the plasma membrane. The plasma membrane is a continuous double-layer of phospholipids, interweaved with cholesterol and proteins. Phospholipids are composed of two fatty acids attached to a phosphate compound as a head.

The phosphate head is water-soluble, also called hydrophilic (water-loving), and the fatty-acids are water-insoluble, or hydrophobic (water-fearing). Since outside the cell is a water-containing, or aqueous, environment, and inside the cell is also aqueous, the phosphate heads of the phospholipids face both the cell's inside and the environment outside the cell, while the fatty acids face the inside of the membrane.

The membrane is fluid, and the molecules are always moving. It has about the same consistency as olive oil.

Jesus in Genesis: 1. The First Word of the Bible

I asked my dad once how do you convince a Jewish person that Jesus is the Messiah. He told me to show them Jesus in the Old Testament. My first thought was like everyone's, the Old Testament (The Tanakh) is for the Jews and the New Testament (B'rit Chadashah) is for the Christians. My dad had it right. Jesus is on every page of the Old Testament; you just have to look. To prove my dad's point, look where Jesus is hiding in plain sight in the very first word of the Bible. God bless you for watching.—John

Planets in Our Solar System and Universe Beyond - Solar System Exploration

#solarsystem #theuniverse #documentary
A solar system is a star and all of the objects that travel around it—planets, moons, asteroids, comets and meteoroids. Most stars host their own planets, so there are likely tens of billions of other solar systems in the Milky Way galaxy alone. Solar systems can also have more than one star. These are called binary star systems if there are two stars, or multi-star systems if there are three or more stars.

Treta no Espaço e SpaceX Indo Para a Lua - Space Today TV Ep.1461



Camisetas, e muitos produtos para vocês. Visite!


Para fazer parte do seleto grupo dos apoiadores!!!


O mundo da astronáutica está em chamas nesses últimos dias.

Serão duas notícias em um único vídeo.

Primeiro é o vazamento da ISS, isso está dando muito pano para manga.

Desde que foi anunciado que o vazamento foi causado por um pequeno buraco interno e que foi feito na produção da Soyuz, ou de maneira deliberada, começaram a pipocar as teorias da conspiração.

Uma parte da imprensa russa, chegou a dizer que o furo foi feito por astronautas americanos para antecipar o retorno para a Terra.

Imediatamente, a NASA e a ROSCOSMOS vieram a público para acabar com o mal entendido.

Disseram que isso é um absurdo, que dentro da ISS não existe essa divisão política, que lá é um ambiente de paz e de compartilhamento.

Os diretores das duas agências irão se encontrar em Outubro antes do próximo lançamento para conversar e verificar que está tudo bem.

Essa história ainda vai dar muito pano para ser conversada.

A outra notícia é da SpaceX e do Elon Musk, não, não é o cigarro que ele fumou no Joe Rogan não.

A SpaceX soltou um tweet dizendo que ela já assinou o primeiro contrato com o primeiro passageiro que irá voar no BFR para dar uma volta ao redor da Lua e voltar.

No tweet a empresa fala que esse é um importante paraíso para que todos em breve tenham acesso a viagens espaciais.

E disse que as novidades de forma completa serão anunciadas na próxima segunda-feira, dia 17 de Setembro de 2018.

Não foi falada data, nome, como, e nem porque, ou seja, foi jogada uma bomba, e agora vamos passar o final de semana especulando.

O que vocês acham, vai antes ou depois de 2022?

Qual o preço da passagem, menos ou mais de 100 mil dólares?

Vocês têm até segunda-feira para fazer suas apostas, e assim que sair a notícia eu trago ela aqui no canal para todos vocês.

About TEDx, x = independently organized event
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
