Key Exchange
 
03:29
This clip from the 2008 Royal Institution Christmas Lectures shows a simple demonstration of how two people can agree on a secret key, even though all of their communications are carried out in public. In the electronic world, secret key exchange allows computers to communicate securely, and is used, for example, when you give your credit card information to an on-line shop. You can watch the 2008 Royal Institution Christmas Lectures in full at: http://research.microsoft.com/~cmbishop or by visiting the Royal Institution web site. There is a dedicated web site to accompany the 2008 Christmas Lectures, with ten interactive games as well as downloadable PDF instructions for experiments which can be conducted at home or at school: http://www.rigb.org/christmaslectures08

Double Slit Experiment explained! by Jim Al-Khalili
 
09:08
"If you can explain this using common sense and logic, do let me know, because there is a Nobel Prize for you.." Professor Jim Al-Khalili explains the experiment that reveals the "central mystery of quantum mechanics" - the double slit experiment. Watch the full lecture here: http://www.youtube.com/watch?v=wwgQVZju1ZM Sometimes called the "two-slit" or "Young's" experiment, it demonstrates that matter and energy can display the characteristics of both waves and particles, establishing the principle known as wave-particle duality. Furthermore, it questions the role of the observer in the outcome of events and demonstrates the fundamental limitation of an observer to predict experimental results. For this reason, Richard Feynman called it "a phenomenon which is impossible ... to explain in any classical way, and which has in it the heart of quantum mechanics. In reality, it contains the only mystery [of quantum mechanics]," (see more at http://en.wikipedia.org/wiki/Double-slit_experiment).

Starting in Crypto with $1,000? What I'd do if I was starting investing in cryptocurrency today
 
11:00
Want to start investing in cryptocurrency like Bitcoin? Here's what I'd do if I was starting from scratch with $1,000 today. Quite frankly, it boils down to simplicity. A lot of people see the historical returns of cryptocurrency and want to get super aggressive. DON'T DO THAT. Here are my thoughts on what I'd do if I had $1,000 to invest in crypto and I was starting over from scratch. 1. I would buy $250 worth of Bitcoin (BTC) and $250 worth of Ethereum (ETH) today. 2. Then I'd wait 2 weeks to dollar cost average my position out. 3. Then I'd repeat step 1, buying another $250 worth of BTC and ETH each. 4. As all of this is happening, study and learn everything you can. Only then if you want to dive into smaller altcoins, should you slowly dip into those crazy waters. Buy Bitcoin, Ethereum and Litecoin on CoinBase and get $10 worth free: https://cryptobobby.com/coinbase Secure your Crypto with a Ledger Nano S: Amazon (faster shipping): https://cryptobobby.com/ledger-amazon Ledger (slower shipping, but cheaper): https://cryptobobby.com/ledger Get a Free Trial of Coinigy (the trading/charting software I use): https://cryptobobby.com/coinigy Follow me on Steemit: https://steemit.com/@cryptobobby Follow me on Twitter: https://twitter.com/crypto_bobby Join the Facebook Group: https://www.facebook.com/groups/140921189836895/ *Some of these links may be affiliate links, meaning if you click and purchase something, I may receive a small commission at no additional cost to you.

Thanks! * ** This is not financial advice and these are simply my own opinions, as such, this should not be treated as explicit financial, trading or otherwise investment advice.

The Third Industrial Revolution: A Radical New Sharing Economy
 
01:44:59
The global economy is in crisis. The exponential exhaustion of natural resources, declining productivity, slow growth, rising unemployment, and steep inequality, forces us to rethink our economic models. Where do we go from here? In this feature-length documentary, social and economic theorist Jeremy Rifkin lays out a road map to usher in a new economic system. A Third Industrial Revolution is unfolding with the convergence of three pivotal technologies: an ultra-fast 5G communication internet, a renewable energy internet, and a driverless mobility internet, all connected to the Internet of Things embedded across society and the environment. This 21st century smart digital infrastructure is giving rise to a radical new sharing economy that is transforming the way we manage, power and move economic life. But with climate change now ravaging the planet, it needs to happen fast. Change of this magnitude requires political will and a profound ideological shift.

Dash: Merry X Mas 2015 = P15E11
 
01:05
Merry X Mas 2015 and a Happy Successful 2016 to all the Dash followers and supporters ! Dash is DigitalCash Dash is a decentralized cryptographic currency that works similar to Bitcoin, but fixes many of Bitcoin's problems. Dash's InstantX technology makes transactions almost instant, meaning it is suitable for in-person trades and point-of-sale purchases. Not only that, but Dash is truly private, meaning that nobody can mine the blockchain to find details of your purchases or financial history. You wouldn't advertise your credit card statement--why advertise your crypto purchases? Dash is built from Bitcoin's core code, meaning that it remains compatible with systems that are already designed to work with Bitcoin. The creator of Dash, Evan Duffield, works with a "core team" of almost 20 people to continually improve the Dash code and ecosystem. Since Dash implemented its self-funding mechanism, a number of new developers have begun working on various aspects of the project as well, including retail point-of-sale and vending machine integration. Dash's masternodes enable investors to earn a 10+% annual return on investment while performing vital services for the network. Masternodes power both the privacy and instant transaction features of Dash. Not only that, but masternode owners are able to vote on which projects will receive Dash's monthly self-generated budget funding. Dash's budget system provides tens of thousands of dollars in recurring funds, every month, which masternode owners allocate to projects designed to improve the Dash ecosystem. https://www.dash.org

The Bitcoin Revolution (Documentary) Hidden Secrets Of Money Episode 8
 
01:14:26
Bonus Features: http://www.hiddensecretsofmoney.com Today, mankind stands at a crossroads, and the path that humanity chooses may have a greater impact on our freedom and prosperity than any event in history. In 2008 a new technology was introduced that is so important that its destiny, and the destiny of mankind are inextricably linked. It is so powerful that if captured and controlled, it could enslave all of humanity. But if allowed to remain free and flourish - it could foster unimaginable levels of peace and prosperity. It has the power to replace all financial systems globally, to supplant ninety percent of Wall St, and to provide some functions of government. It has no agenda. It's always fair and impartial. It can not be manipulated, subverted, corrupted or cheated. And - it inverts the power structure and places control of one's destiny in the hands of the individual. In the future, when we look back at the 2.6 million-year timeline of human development and the major turning points that led to modern civilization - the creation of farming, the domestication of animals, the invention of the wheel, the harnessing of electricity and the splitting of the atom - the sixty year development of computers, the internet and this new technology will be looked upon as a single event...a turning point that will change the course of human history. It's called Full Consensus Distibuted Ledger Technology, and so far its major use has been for cryptocurrencies such as Bitcoin....but its potential goes far, far beyond that. The Crypto Revolution: From Bitcoin to Hashgraph is our latest episode of Hidden Secrets of Money. It’s about the evolution of cryptocurrencies and full consensus distributed ledger technology, and how they will change our world. I believe that this video is by far the easiest way for the average person to gain an understanding of what cryptocurrencies are and how they work, but more importantly, the immense power of full consensus distributed ledger technology and the impact it will have on our daily lives. I have an absolute passion for monetary history and economics, and I love teaching them. Cryptocurrencies are our future, and there is no escaping it… this is the way everything will be done from now on. But, we now stand at a crucial turning point in history. Full consensus ledgers such as Blockchain and Hashgraph have the power to enslave us, or free us… it all depends on how we choose to use them. If we choose to support centralized versions issued by governments and the financial sector we will be granting them more control over our daily lives. Politicians and bureaucrats will be able raise taxes instantly, whenever they want, on every dollar you make as you make them, and every dollar you spend as you spend them. If they think the economy needs stimulating they'll be able to enforce huge negative interest rates, effectively punishing you for not spending everything you earn before you earn it. They'll be able to decide where you can go and where you can’t, what you can buy and what you can’t, and what you can do and whatever they decide you can’t do… and if they don't like you, they can just disconnect you from the monetary system. So, will the monetary system become fully distributed and help to free mankind, or will it be centralized and enslave us? The choice is in front of us right now, and our decisions will create our future. I believe that this will be a binary outcome, there is no middle ground, it will either be one future or the other. The question is, will it be the future we want? Or the future they want? I’m a precious metals dealer and one thing I’ve learned is that gold, silver, and now free market decentralized cryptocurrencies, represent freedom. Because of this knowledge I started investing in crypto currencies long ago and also became one of the first precious metals dealers to accept bitcoin as payment for gold and silver. I would really appreciate it if you could share this video with everyone you know. I think it’s very important that as many people as possible find out about the changes to the global monetary system that are happening right now… nothing will affect us more, and everyone’s future depends on it.

Modern Morality and the Ten Commandments
 
27:06
When we consider the great empires of the past, we should learn the lessons of history. One of the major causes of the decline of Rome was the disintegration of family. Divorce, adultery and indulgence devastated family unity and values. In contrast, the Ten Commandments show the way to lead a proper, moral life!

10 Interesting Facts About New Year | New Year's Eve Celebration
 
07:58
10 Interesting Facts About New Year Number 10: New Year in History. The earliest recorded festivities in honor of a new year's arrival date back some 4,000 years to ancient Babylon. For the Babylonians, the first new moon following the vernal equinox, the day in late March with an equal amount of sunlight and darkness, heralded the start of a new year. The occasion was marked with a massive religious festival called Akitu, a Sumerian word for barley. In 46 BC, Julius Caesar introduced the Julian calendar, which closely resembles the more modern Gregorian calendar that most countries around the world use today. As part of his reform, Caesar instituted January 1 as the first day of the year. Number 9: January's Fitting Meaning. January is named after the Latin word for door, since January is the door to the year and an opening to new beginnings. The month is conventionally thought of as being named after Janus, the god of beginnings and transitions in Roman mythology. Janus is depicted as having two faces, since he looks to the future and to the past. He presided over the beginning and ending of conflict, and hence war and peace. Number 8: Christian Feasts. According to the Gospel of Luke, in keeping with the Jewish Law, Jesus was circumcised eight days after his birth. Considering December 25 as the traditional date of Jesus' birth, January 1 becomes a significant date among Christians. For many Anglican and Eastern Orthodox Churches, January 1 is appropriately celebrated as the Feast of the Circumcision. For Roman Catholics, it is celebrated as the Feast of the Holy Name of Jesus and the Solemnity of Mary, the Mother of God. Number 7: Auld Lang Syne. Written by Robert Burns in 1788, Auld Lang Syne is a Scottish poem well known in many countries, especially in the English-speaking world. It may be translated into standard English as "old long since", or more idiomatically, "long, long ago", "days gone by", or "old times". The essence of the song is all about preserving old friendships and looking back over the events of the year. Number 6: Interesting Traditions. From kissing at the stroke of the clock, to eating black-eyed peas, to lighting dozens of fireworks, to wearing polka dots, to throwing coins, and to jumping as high as one can possibly jump, January 1 is buffeted with so many traditions. Here's one interesting tradition. In some Latin American countries, including Mexico and Brazil, it's believed the color of your undergarments will influence what kind of year you'll have. Tradition holds that yellow underwear will bring prosperity and success, red will bring love and romance, white will lead to peace and harmony, and green will ensure health and well-being. Number 5: New Year's Resolutions. In a recent survey from YouGov, the online polling firm, only 32 percent of people said they weren't planning on making New Year's resolutions - meaning most people do plan to set themselves new goals for the coming 12 months. Here's the top 5 resolutions people told YouGov they were committed to fulfill in 2018. Eat better - 37 percent, exercise more - 37 percent, spend less money - 37 percent, take care of one self - 24 percent, and read more books - 18 percent. Number 4: More Stolen Vehicles. Statistics show that New Year's Day is the top holiday for car thefts, according to the National Insurance Crime Bureau. For example, in 2013, 2,184 cars were stolen on New Year's Day, 1,998 on Halloween, and 1,972 on Memorial Day. The day with the least stolen cars is Christmas Day, with 1,224 cars stolen. Number 3: New Year's Eve Ball Drop. The Times Square New Year's Eve ball drop came about because of a ban on fireworks. The first ball in 1907 was 700 pounds and was lit with 100 25-watt lights. The current ball puts the old one to shame (thanks to technology). Today, it is covered in 2,688 crystals, is lit by 32,256 Philips Luxeon LED lights, weighs 11,875 pounds, and is 12 feet in diameter. Number 2: First and Last. If you'd like to be among the first to welcome the New Year, then you'll want to visit the tiny Pacific island nation of Kiribati. It's located in the world's earliest time zone, so it's always the first place on Earth to welcome a new year. As for the last place to ring in the coming year? That title belongs to American Samoa in the South Pacific Ocean. Number 1: New Year's Movie. Without any doubt, the gold award of best New Year's Eve movies goes to When Harry Met Sally. It's a perfect romantic film telling that Harry and Sally are intimate friends for years, but they fear sex would ruin their friendship. To make audience happy, Harry finally confesses his deep love for Sally. And his best and classic words are still touching women's hearts. ''It's not because I'm lonely, and it's not because it's New Year's Eve, I came here tonight because when you realize you want to spend the rest of your life with somebody, you want the rest of your life to start as soon as possible."
