The question shows a misunderstanding of why the Middle Ages were medieval. It's not that the people who lived in those times did not know any better. They did. In particular, they had good Roman books about military strategy, tactics and logistics; for example, they had and they actually read Vegetius's De re militari; the book was copied over and over, and ...

Honestly the 'modern' military theory that would give Lord Gary the biggest advantage would be modern attitudes towards hygiene. It was extremely common in the time period you're talking about for a force to lose more troops to dysentery and other diseases than they lost in actual combat. By taking a very firm attitude towards latrine maintenance and ...

Befriend and hang out with fellow passenger, Margaret (Molly/Maggie) Brown then follow her to lifeboat #6 which historically will have available seats.

As soon as a lifeboat launches, volunteer to be in it. At first there were quite a lot of people who hesitated to go into a little wooden boat in the middle of the Atlantic, when the big reassuring liner still had power and light and was merely stopped. Here is the wikipedia link looked up by DevSolar. Pryftan is right, a source never hurts.

You can't get anywhere close to that technology level. The best you could do is work to increase their life expectancy. Teach them farming. Teach them how to get water from a river into their fields. Teach them about cleanliness and basic first aid medical care. If your group of people can boost the life expectancy long enough to actually have ...

No. But I'm answering this from a different perspective: world population. 10,000 years ago, the world population was around 10-20 million. And this population was spread across the globe. Your experts would only find small villages, consisting on average of several hundred people at most. Even if your experts could convince everyone to do exactly as ...

Just track it Since: Nothing other than foreverium is forever You're a time traveller There's no real reason to worry about this ring, whoever has it right now is as ephemeral as any security system. All you need to do is know where and when the ring is at any given point and you can pick the thing up. Wait until the end of time if you want to and just ...

The correct answer is to just join the crowd of time travelers getting their own foreverium ring at Evaporation Point. Think about how you've described your foreverium ring for a second. It's immutable, unalterable, and undecay-able. So, what happens when the universe goes old? It survives heat death, it survives particle decay, and it survives at the ...

No Barring the existence of some Illuminati-type organization who watches for people like you, anyway. Most of these tech companies succeeded because they had the good fortune to introduce a service or good into the market at the right time and had the right strategies to defeat all their competitors. It would be difficult to see how an influx of money ...

Buy a first class ticket If you had a child with you would increase it more. You could also have your life jacket with you and wait near the lifeboats. Being a woman would also increase the odds. Even if you were a first-class passenger with a higher likelihood of getting a seat in a lifeboat, your chances of getting that seat increased if you were a ...

Let's manage our expectations a little, and consider a fairly discrete (but certainly iconic) 21st century technology: firearms. But let's manage expectations further and try to create a modern firearm's 14th-century ancestor: the cannon. A cannon is, crudely, a lump of metal with a big hole at one end and a tiny hole at the other, into which you pour ...

You're on deck, which is the most important thing. Your survival odds are already waaay up. It'll be cold on deck. Wear a big coat. Underneath your coat, wear a good dry suit with some high-quality thermals underneath (possibly battery heated ones). The photos on the Wikipedia page notwithstanding, a drysuit needn't make you look like an astronaut, ...

No As it is you will be lucky to have any impact at all. You have a lot of dead weight and you are missing the most important fields. Things your forgot The first thing you need is better food production, for that you need biologists, agricultural scientists and soil scientists. without them, most of your effort is wasted and you may do more harm than ...

Lots of excellent stuff here so here is my 2 cents. One of the biggest "modern" warfare things that Lord Gary could adopt that was not very common is the concept of Meritocracy in his army. Throughout history this always seems to present an odd dichotomy, as some of the most terrifying and effective Armies in history had at least a bit of this going on. ...

The simplest way to ensure that you yourself - and as many others as possible- survive the Titanic disaster is to distract the forward lookout at the critical moment so that he does not give warning of the iceberg ahead until it is too late to turn the ship... if at all. If the means by which you distract the lookout is to offer him the use of your period-...

Not a full 21 century world, but we can get close to it in some ways. 10,000 members tribe in post-glaciation Germany would be HUGE, but let's take it for a fact. One of the problems is that 10,000, even 20,000 people is not even closely enough to accomplish our task. And German lands are not fertile enough to support big preindustrial population. Here is ...

When you are done with the ring, give it to yourself the next time you need it and then when you need it again go back to when you were last finished with it to receive it from your past self. The ring then only exists when you are using it and there's no need to store it at all. If it's stolen while you have it, go back to before that and tell your past ...

Locate crew member Jack Phillips, the ship's "senior wireless operator". Making a few changes to his timeline this evening will increase your chances of survival immensely. The general idea is that the SS Californian was in the vicinity and had the capacity to save essentially everyone on board the Titanic, if only they were aware of the disaster. On that ...

Brianism On 33 A.D. a man called Brian was recognized by the locals of Jerusalem as the Messiah. He said he wasn't the Messiah, but as one of his disciples attentiously noted, only the true Messiah would deny his own messianity. He was later imprisoned on charges of terrorism and condemned to crucification. Pontius Pilate offered the people the pardon of a ...

There are several relevant Clausewitzian, Jominian, and Machiavellian concepts that would benefit Lord Gary. While some of these seem obvious to us, recall that most wisdom seems rather obvious in retrospect. Clausewitz: War is an extension of politics, and wars have political goals. Putting 'war' in the 'politics' box doesn't reduce war, it expands the ...

Ask yourself. No, seriously, ask yourself. You've got a time travel machine. Why are you asking the internet whether your scheme will work? Go forward in time and ask yourself whether it worked. (To be honest, if you've got access to a time machine and your scope of usage is simply "make some money with the stock market", you've got a critical failure ...

Get in your time machine and leave. Bring your own dry suit and Arctic survival gear so you can go in the water without risking your life Bring your own inflatable life raft Lock the proper doors so the hoi poloi in steerage can’t get to the life boats, ensuring there is adequate room for you and no pushing and shoving Use the pistol you brought back with ...

There will be immediate civil unrest for sure. What happens after that probably depends on how it resolves. The city might split into different areas that war with each other, or the NYPD might take over the whole thing and proclaim a military dictatorship. Who knows? In any event, 95% of the city is likely to be dead in 6 months. There's no way any ancient-...

No There is way more knowledge between 8000BC and now than you could possibly stuff into any 120 people, no matter how smart they are. And they won't be around long enough to spread everything that they know to others. Just for reference, a child today goes to school for ~12 years, followed by 4 years of university education, followed by maybe some 4+ ...

Energy I think other answers do a pretty good job of covering most of the issues. I would just like to add a few points: The biggest bottleneck to the advance of civilization is the available energy The biggest bottleneck to a fast-forward of civilization is domestication Major advances in human history usually occur when humans learn to harness a new ...

would modern warfare theory be useful to Gary against his enemies? How would his medieval army, tactic, and strategy change using only resources available at the time? I am not an expert of modern warfare, but I doubt what we call modern warfare would be of any use in middle ages. Let's look at some of the key points of modern warfare Aerial supremacy and ...

Modern tactics would be probably of less use than knowing historical tactics. There were a bunch of effective ideas scattered across Middle ages and early Renaissance, that work with medieval resources. Just some ideas off the top of my head: Make your peasants performing some basic training all year long, so they are more fit and skilled when the time ...

The first thing your time traveller will do is: a) die of dysentery or some other water borne disease; or b) be patient zero of a plague that wipes out a large proportion of the city he is in. Assuming he manages to avoid the above, the best thing to do is become a healer. As long as he makes a name for himself, he will be allowed to join the temple of ...

Well, from it sounds like, the lower decks for the poor folks were locked off which made it impossible to get outside. So, don't go there. From what I've seen, the boat rose up and then cracked in half. The middle would be bad because you're going to end up plummeting into the water along with a whole mess of wood, metal, and screaming bodies. I don't ...
