Territories that today belong to Lithuania were claimed by Poland and Soviet Russia alike - while these two were waging a war in the direct vicinity of Lithuania. » SUPPORT THE CHANNEL Patreon: https://www.patreon.com/thegreatwar Become a member: https://www.youtube.com/channel/UCUcyEsEjhPEDf69RRVhRh4A/join » OUR PODCAST https://realtimehistory.net/podcast - interviews with World War 1 historians and background info for the show. » BUY OUR SOURCES IN OUR AMAZON STORES https://realtimehistory.net/amazon * *Buying via this link supports The Great War (Affiliate-Link) » SOURCES Balkelis, Tomas, “From Self-Defense to Revolution: Lithuanian Paramilitary Groups in 1918 and 1919”, in Fleishman, Lazar & Weiner, Amir (eds.)

Why some Americans’ votes count more than others. Watch more of our election coverage: http://vox.com/ElectionVideos In the 2000 US presidential election, the Democratic candidate got half a million more votes than the Republican. The Democrat lost. Sixteen years later the same thing happened again. In the US, if you run for president, it does not actually matter how many people in the country vote for you. What matters instead is an arcane system for selecting America’s head of state called the Electoral College. The Electoral College is the reason the US has something called “swing states,” and it’s the reason those places get to decide the future of the country. It’s the reason presidential candidates almost never campaign in the country’s biggest cities. And more recently, it’s also the reason that Republican candidates have been able to eke out victories in the presidential election without actually getting the most votes. The Electoral College makes some Americans’ votes more powerful than others. In fact, that’s part of the reason we have it to begin with; in the country’s early years, the Electoral College helped give the votes of Southern Whites more weight than the votes of Northerners. The idea at its core, that certain votes simply matter more than others, is baked into the American tradition. In the 2020 election, it may decide the winner. Further reading: The historian Alexander Keyssar’s book “Why Do We Still Have the Electoral College?” takes you through the history and function of the Electoral College: https://www.hup.harvard.edu/catalog.php?isbn=9780674660151 For the bite-sized version of that history, Keyssar also wrote this piece in the New York Times: https://www.nytimes.com/2020/08/03/opinion/electoral-college-racism-white-supremacy.html The Times also had a great interactive feature on where the 2020 candidates actually spent money: https://www.nytimes.com/interactive/2020/10/17/us/politics/trump-biden-campaign-ad-spending.html Pew has a breakdown of how democracies around the world elect their head of state, which really shows what an oddball the US is: https://www.pewresearch.org/fact-tank/2016/11/22/among-democracies-u-s-stands-out-in-how-it-chooses-its-head-of-state/ More on why today’s Electoral College gives Republican presidential candidates a structural advantage: https://www.vox.com/policy-and-politics/2019/9/17/20868790/republicans-lose-popular-vote-win-electoral-college Vox.com is a news website that helps you cut through the noise and understand what s really driving the events in the headlines.

I continue rennovating the abandoned ww2 bunker that is in my back garden. In part 7 we focus on building the escape hatch. The bunker never had a hatch previously, it just had a concrete slab on top with an air gap. But I figured it would have been better to have a backup exit if things were going down! So now that the escape ladder was built, it made sense to build a folding escape hatch in the air vent shaft. Stay tuned for more world war 2 bunker updates soon!

Building an off grid workshop, a tiny cabin, with heavy hemlock timbers is taking way longer than I expected - it s heavy work and cutting, shaping and fastening the timbers together is tedious and time consuming. Temperatures are dropping quickly and the first snow of the season falls on the cabin while local wildlife is very active preparing for winter - moose, deer, fox and bear show up on my trail cameras around the homestead.

But when the Allies finally decided to invade Italy in 1943, they quickly became stalemated by a series of expert-crafted defensive lines created by the German general Albert Kesselring. Join us as we explore exactly how the invasion that was predicted to last only a few months turned into a grueling ordeal that lasted all the way up until the Axis surrender, and cost the Allies over 300,000 casualties.

We re taught to believe that America is the greatest country on earth and that it couldn t possibly get any better. Let s put that claim to the test. In this episode, we ll compare the US to other wealthy nations using several key metrics: "low-skilled" job compensation, vacation time, length of the work week, and paid parental leave. The results may surprise you.

Albert Einstein is, well, Albert Einstein. But, was he right? It seems like a silly question, but, in fact, there’s some history behind it. On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are investigating what it took to prove Einstein right, with Dr. Jim Gates, theoretical physicist and Professor and Center Director of the Brown University Theoretical Physics Center. Jim is also the co-author of Proving Einstein Right: The Daring Expeditions that Changed How We Look at the Universe. We start with some history. Jim tells us about Einstein’s discoveries about space and time in 1905. You’ll learn about the “happiest thought” of Einstein’s life. We discuss how he came to his theory of general relativity and theory of special relativity. You’ll also learn why, even though he first started working on the ideas in 1905, it took him over a decade to get them right. Find out what it takes to provide evidence for mathematical theories in the real world. We discuss Einstein’s exposure to the real world and how that informed his thought process. Jim explains why being a scientist involves swimming in a sea of information. We ponder if Einstein ever thought his theories were incorrect, and Jim tells us why math is magical. Then, we answer fan-submitted Cosmic Queries! Is general relativity incompatible with quantum mechanics? If so, why? Is there a bigger idea that encompasses both ideas? We dive into String theory and how that might play into the equation. We investigate “gravitons” and how their existence would re-shape science. Are the strings in String theory made of something? We explore the cosmic microwave background and debate if a cosmic gravitational background could also exist. Lastly, you’ll hear why some stars in the night sky might be duplicated due to the bending of light. All that, plus, we answer the most important question of all – who has a better mustache? Neil deGrasse Tyson or Albert Einstein? Thanks to our Patrons Beverly Bellows, Christopher Mank, Darrell R. Scott, Eric Burgess, Pike Persons, AK Llyr, Nicholas Belsten, and Samuel D Fairchild for supporting us this week.

This course is for you! Exercises in this video: 1. An object with mass M is a distance R from the center of the earth. Another object with mass 2M is at a distance 3R from the center of the earth. What is the ratio of the forces between each object and the earth? 2. What is the force of gravity between the Earth and a pineapple with mass of 1kg, if the pineapple is falling near the Earth’s surface? 3. What would the acceleration due to gravity be on a planet with half the radius, but twice the mass of Earth? 4. The ISS orbits with an average altitude of 410 km. What is its orbital velocity? What is its orbital period? 5. Extras Credit: What is the orbital velocity of an object orbiting the Earth at a height of 35,800 km above the Earth’s equator? (Don’t forget to add in the Earth’s radius!). What is the orbital period?
