Film Theory: Titanic is about Time Travel... No REALLY!
Titanic is a movie that has stood the test of time... and has one of the BIGGEST unanswered questions of any movie. No, I don't mean could they both fit on the door if Rose had just moved over a little. I mean the question is Jack a time traveler sent to make sure the Titanic sinks? Yes, that age old question. Well Theorists, today we are going to answer that once and for all!
India's Solar Canals. Lateral thinking at its finest!
Solar Power is set to be the dominant transformative form of power on the mighty subcontinent of India as it moves away from its dependence on coal and towards a more sustainable future. But land is at a heavy premium there, so the engineers put their thinking caps on and came up with a solution so effective it has solved more problems than even they anticipated!
As you know artillery is my trade and its interesting to see what futuristic sci-fi style artillery could be made. Some of these designs are actually pretty cool to vision as being something put into service in the future!

1. Creeping barrage.
2. While wheels or tracks can probably help reposition it faster, legs might be better for more unstable terrain.
A lunar economy or moon economy is fast approaching, with plans in place for manned return missions to the moon this decade!
It’s well known that we have the technology to get there, yet the last manned mission, Apollo 17, was back in 1972.
This has led many to conclude that whilst we possess the technology to get there, the real problem is the economics. Once you start thinking of it as an economic problem, a whole new interstellar world of ideas and questions start to emerge…
Like what a lunar economy could look like? Why the so-called MUSCLE strategy will determine economic activities? How the business model for space exploration has changed? OR even how space could be regulated? These are just some of the questions we’re going to be addressing in this video.
Under the assumption of a spherical planet with uniform density, and ignoring relativistic effects as well as friction, a gravity train has the following properties:[3]
The duration of a trip depends only on the density of the planet and the gravitational constant, but not on the diameter of the planet.
The maximum speed is reached at the middle point of the trajectory.
For gravity trains between points which are not the antipodes of each other, the following hold:
The shortest time tunnel through a homogeneous earth is a hypocycloid; in the special case of two antipodal points, the hypocycloid degenerates to a straight line.
All straight-line gravity trains on a given planet take exactly the same amount of time to complete a journey (that is, no matter where on the surface the two endpoints of its trajectory are located).
On the planet Earth specifically, since a gravity train's movement is the projection of a very Low Earth Orbit satellite's movement onto a line, it has the following parameters:
The travel time equals 2530.30 seconds (nearly 42.2 minutes, half the period of a Low Earth Orbit satellite), assuming Earth were a perfect sphere of uniform density.
By taking into account the realistic density distribution inside the Earth, as known from the Preliminary Reference Earth Model, the expected fall-through time is reduced from 42 to 38 minutes.[4]
For a train that goes directly through the center of the Earth, the maximum speed is equivalent to Earth's first cosmic velocity, also known as its orbital velocity – that which will bring a rocket or other projectile into orbit around Earth (a slower projectile falling back to Earth, a faster one escaping Earth's gravity altogether) – about 7,900 meters per second (28,440 km/h), equivalent to Mach 23.2 at sea level and standard temperature.
To put some numbers in perspective, the deepest current bore hole is the Kola Superdeep Borehole with a true depth of 12,262 meters; covering the distance between London and Paris (350 km) via a hypocycloidical path would require the creation of a hole 111,408 metres deep. Not only is such a depth 9 times as great, but it would also necessitate a tunnel that passes through the Earth's mantle.
Artificial Chloroplasts. Nature shows us how to ditch petrochemicals!
Nature already knows how to convert energy from carbon dioxide and sunlight. After all it's been doing it for millions of years in the form of photosynthesis, the fundamental building block for all life on earth. But although the process is extremely efficient, it's not very fast. Now scientists have discovered how to mimic nature's magic in a laboratory, and speed it up so much that it could become an industrial scale replacement for petrochemicals, allowing us to keep more and more crude oil in the ground where it belongs.

Nanobionics: Spinach that can send emails and plants that detect poison! 4 Feb 20214 February 2021Last updated at 07:28
Plants are already amazing, they can use light from the Sun to make food for themselves, produce seeds to make new plants and most importantly they take in carbon dioxide and release oxygen from their leaves which humans and animals need to breathe.
But now scientists have been adding tiny nanobionic sensors to plants so they can do even more incredible things from detecting explosives and discovering dangerous elements underground.
The experiments are part of a big research projects into plant nanobionics, which is technology that gives plants new skills.
Fancy more science stories...
Why wombats have CUBE-SHAPED poo!
Researchers have found that they can use plants to detect and monitor levels of arsenic underground.
Scientists at Singapore-MIT Alliance for Research and Technology (SMART) added nanosensors to the plants, which don't harm the plant, and which allow the sensors to monitor the levels of arsenic taken up by the plants from the soil.
The scientists are pleased with this new research because it is the first of its kind and it takes less time and equipment to find arsenic when using the plants.
Scientist Tedrick Thomas Salim Lew said: "We envision that this innovation will eventually see wide use in the agriculture industry and beyond."
That's not all, spinach plants can also be used for amazing innovations too.
achusetts Institute of Technology (MIT) also found that they can use spinach to detect landmines and communicate by email...sounds unbelievable doesn't it, let us explain.
By using nanotechnology engineers transform the spinach plant by putting electronic sensors on their leaves which helps the roots know if they come into contact with certain chemicals.
The spinach roots can detect nitroaromatics, which are normally found in explosives.
The plant then gives gives off a signal which is detected by an infrared camera, which can then send an email alert to scientists.
Theorists, have you ever wanted to TASTE what you see on screen like you were in the Willy Wonka movie? It would be amazing to watch something like the Food Network and be able to get a taste of all the delicious looking food we see. What if I told you that you CAN do that? Or rather, you will be able to do that SOON? Science is getting close and I, for one, CANNOT WAIT! When, where, and HOW will this happen? Watch to find out!
Fusion Has Major Problems That No One Is Telling You About
We investigate why Fusion is neither cheap, nor unlimited when it comes to producing Electricity. Contrary to the claims of its proponents.
This video explores some of his most damning criticisms of humanity’s attempt to make electricity from Fusion. Based on the Articles by Princeton Plasma Physicist, Daniel Jassby, linked below.
In 1965, when two cosmonauts landed back on Earth in the snow-covered forest of Russia's Urals region, they feared their simple pistols wouldn't be enough to fight off the giant bears or hungry packs of wolves that roamed the area.
Although the men survived the experience without coming across any animals, the concern remained. How could cosmonauts better protect themselves in case they landed in a dangerous place?
That's how the primary survival weapon for Soviet cosmonauts, the TP-82, came to be. Created in consultation with a former cosmonaut, this weapon was designed specifically for the harsh environment in Soviet territory, not for fighting Americans.
According to documents and interviews of former cosmonauts, it was used by space explorers for almost 20 years. Dozens of astronauts visiting the International Space Station have practiced with it. Few have even spoken publicly about it.
Even though it's an open secret, to this day, the Russian Federal Space Agency still refuses to talk about the weapon. But, in case there's any doubt about the TP-82's existence, there's one on display in a Russian history museum.
Some in the American space program during the Cold War remain skeptical of its stated non-combat purpose...

2018 AG37 (nicknamed FarFarOut) is a distant trans-Neptunian object that was discovered 132.2 ± 1.5 AU (19.78 ± 0.22 billion km) from the Sun,[6] farther than any other currently observable known object in the Solar System.[3][7] Imaged in January 2018 during a search for the hypothetical Planet Nine,[8] the confirmation of this object was announced in a press release in February 2021 by astronomers Scott Sheppard, David Tholen, and Chad Trujillo. The object was nicknamed "FarFarOut" to emphasize its distance from the Sun.[3] With an estimated diameter of 400 km (250 mi), it is near the lower limit for a dwarf planet candidate.
At a very faint apparent magnitude of 25, only the largest telescopes in the world can observe it.[1] Being so far from the Sun, 2018 AG37 moves very slowly among the background stars and has only been observed nine times in the first two years.[5] It requires an observation arc of several years to refine the uncertainties in the approximately 1,000-year orbital period and determine whether it is currently near or at aphelion (farthest distance from the Sun). As of 2021 the nominal JPL Horizons solution has it coming to aphelion around the year 2158,[6] whereas Project Pluto shows it reached aphelion around 1951.[9]

The Secret History of Fighter Aircraft Engine Development in WW2
The development of piston-aero engines were the dominant mechanism in determining fighter aircraft performance from 1939-1945.
This lecture focuses on key technical and organizational differences between the German and British efforts which had key impacts on both the airframe aerodynamic design and engine characteristics of both aircraft. The speaker presents a guided tour through the key difficulties experienced by German and British aviation engineers - using access to unique archival material, including the personal papers of Professor Willy Messerschmitt, and Ernest Hives, Technical Director at Rolls-Royce.
Speaker: Calum Douglas BEng MSc: Powertrain Design Engineer, Historian
Calum Douglas worked in Germany for Toyota Motorsport GmbH applying Formula One engine technology to advanced technology demonstrator engines for Toyota Japan road cars division. Returning from Germany, he worked for Jaguar Land-Rover and Mercedes AMG High Performance Powertrains and now runs an engine design consultancy. He began investigating piston engine development in wartime archival records and has spent the last five years researching and writing about it alongside working. He has been invited to speak worldwide to present his engine development historical research, from Scuderia-Ferrari Formula One in Italy, Rolls-Royce, the Royal Aeronautical Society, Renault-Sport and Mercedes AMG Formula-One engine and chassis technical centers. He will publish two books this year, including a translation of the unpublished memoirs of Professor Dr-Ing Karl Kollmann, Chief designer of Daimler-Benz Aero Engines: through the American Society of Mechanical Engines. The book is a collaboration with American gas turbine expert Dr S. Can Gülen, and is entitled "Centrifugal Compressors for Turbo/Superchargers -Theory and Practice: Guidance from the Past – for Modern Engineers and Students". The second is a technical history of piston aero engine development from 1928to 1946, entitled "The Secret Horsepower Race" and is available to pre-order from Mortons Publishing and Amazon.
30 Dirt Cheap Items That Will Be Priceless After The Imminent Economic Collapse
The 2020 economic collapse has demonstrated its ability to wipe out supply chains, drive grocery store prices sky high, and cause massive shortages of everything from toilet paper to meat to aluminum cans.
As we head into the fall, the disaster is only going to intensify, so it is crucial that you take the last days of the summer season to prepare for the worst.
This list from UrbanSurvivalSite details 28 of the most important items to add to your stockpile as the economic collapse wreaks havoc on the United States. Keep watching until the end to make sure you don’t miss a single item. The last thing you want is to notice that key supplies are absent when it’s already too late. After all, although they’re cheap now, as soon as things go south, the value of these supplies will skyrocket overnight.
The good news is that for now most of the supplies that will make the difference between catastrophe and survival when the time comes won’t break the bank. In fact, these cheap goods are things we may take for granted in day to day life. But in a few months, they could be keeping you and your loved ones alive, or be used to barter for other necessary items.
Without further ado, let’s get into the list. Pay close attention, and don’t forget to like and subscribe to our channel so you stay up to date on the situation at hand and the ways in which to stay a step ahead of the financial collapse sweeping the globe.
7 Ways To Pull Carbon From The Atmosphere | Random Thursday
If we are ever going to return the atmosphere to pre-industrial levels, we have to take out some of the carbon we've already put into the sky. Still, carbon capture is a controversial topic and one that many people know very little about. So let's look at 7 carbon capture methods and how they work.

1. Basalt rock dusting - viable in a spaceship?
2. Algae carbon sink - we have large tanks onboard.
3. Electro swing absorption technique - attracts carbon dioxide, then flushes it.
H1MIN: UGS MANTA - Hydrofoil midget submarine
An unusual late WWII design for the German Kriegsmarine was the midget submarine called UGS Manta. A hybrid design of different research bureaus, the idea was to provide a naval vessel with the capabilities of a midget submarine and the speed of a hydrofoil boat.
Hellmuth Walter, a German engineer who pioneered research on underwater air-independent propulsion (AIP) had built a submarine with remarkable underwater speeds. Similar technology was proposed for this design but due to competing interests and costs it was doubtful this could be viable even during wartime. Although an interesting design, it was never built and only a model remained of its existence.

Robots of the future may be softer, squishier and bendier than robots today. This could make them ideal for space exploration. Check out http://kiwico.com/Veritasium50 for 50% off your first month of any subscription!
On Thursday February 18th, 2021 the NASA Perseverance Rover will land on Mars. It is a wonderful robot, made out of steel and wire — but will future robots look like Perseverance? There is an emerging field of research on "soft robots", where the machines are flexible. These soft robots have many advantages over traditional robots — they're safer, lighter, more flexible and can change their shape and size.
NASA is investigating the use of soft robots for space missions. For future visits to Enceladus or Europa, a lander could cut a hole in the ice and then insert a compliant robot through the hole. This robot could then grow and change shape on the other side.
