Help for Time Travellers.

In my novella, “Anatopismo”, one of the characters expresses surprise that a community has electricity. The other character is surprised by this reaction and responds “Why not? It is just wire and magnets.”
I was reminded of this passage since I have started reading “How To Invent Everything: A Survival Guide For The Stranded Time Traveler” by Ryan North (2018, Riverhead Books) ISBN 978-0735220140. A common theme that occurs in this book is that many of humanity’s inventions and discoveries could have been made centuries or even millennia before they were. Sometimes an idea was adopted in one field, but it was a considerable time until it was applied in others. For example, wine was being pasteurized centuries before it was applied to other foodstuffs, such as milk.
How To Invent Everything will probably prove interesting to many readers of this blog, but particularly those interested in long term scenarios. It is packed full of diverse, useful information in an easily readable style. There are a few points of contention. The beer recipes given are rather vague. The comments made about the cloudiness Egyptian-style beer are probably out of date. Staphylococcus are not necessarily harmless. The author also describes yeast as “animals”, which is a pretty basic, avoidable mistake, and makes me wonder about other inaccuracies. You should probably double check any facts from the book before you get into any arguments, but that is a sound policy anyway.
On the topic of verifying information, the book is worth reading just for the comments on the scientific method:
“This is the more accurate theory of combustion that we still operate under today, but we could still be wrong.
Or, more likely, we could still be more correct.
Here’s how you produce knowledge using the scientific method.
An example: maybe you notice (as per step 1) that your corn didn’t grow well this year. For (2), you might ask, “Hey, what the heck, everyone, how come my corn didn’t grow well this year?” You might suspect the drought affected the corn’s growth (3), and so (4) decide to grow corn under controlled conditions, giving each plant different amounts of water but equal amounts of everything else you can think of (sunlight, fertilizer, etc.). After carefully doing that (5), you might conclude (6) that a precise amount of water grows the best corn plants, and (7) let your farmers know. And when your corn still doesn’t grow as well as you want, you might explore (8) and wonder if there’s more to growing great corn than just making sure your corn isn’t thirsty.*
The more ways a hypothesis has been tested, the more likely it is to be correct, but nothing is certain. The best case you can hope for by using the scientific method is a theory that happens to fit the facts as you understand them so far: science gives you an explanation, but you can never say with absolute certainty that it’s the correct one. That’s why scientists talk about the theory of gravity (even though gravity itself clearly exists and can cause you to fall down the stairs), theories of climate change (even though it’s obvious our environment is not the same one our parents enjoyed, or that you’re enjoying right now), or the theory of time travel (even though it’s a fact that you’re clearly trapped in the past for reasons that cannot have any legal liability assigned).
Note that the scientific method requires you to keep an open mind and be willing—at any time—to discard a theory that no longer fits the facts. This is not an easy thing to do, and many scientists have failed at it. Einstein* himself hated how his own theory of relativity argued against his preferred idea of a fixed and stable universe, and for years tried in vain to find some solution that reconciled them both. But if you succeed at following the scientific method, you will be rewarded, because you will have produced knowledge that is reproducible: that anyone can check by doing the same experiment themselves.
Scientists are often seen as turbonerds, but the philosophical foundations of science are actually those of pure punk-rock anarchy: never respect authority, never take anyone’s word on anything, and test all the things you think you know to confirm or deny them for yourself.”


The Soft Core Bag.

Today I am going to introduce what I call my “soft core bag”. This is not a “bug-out bag”, although it could be included in the contents of one.
I have a number of bags and rucksacs, and there are certain items that I would invariably want in one of I was carrying it. Stocking each pack with necessary items is not economically practical, however. Perhaps, I thought, I should have a box containing the necessary items and potential alternatives. This was part of the solution, but I quickly realized many items could be packed together so they could easily be grabbed in one go.
I drew on the lists given in the previous post to select the current loadout.

  • Top left: A small first aid kit. This supplements the items I carry in my skin-level EDC.
  • Directly below the first aid kit in a dark brown camouflage bag is a rain poncho.
  • The white plastic bag beside the poncho contains a toilet roll.
  • Middle top can be see a bag of boiled sweets and a pair of warm gloves. These are sitting on top of a dark green all-weather blanket. You can see some of the shoelaces that are tied to the grommets of this. I intend to add a pair of silver space blankets.
  • Top right, a red and black shemagh. This is a spare/ additional shemagh since I am often wearing one these days.
  • Bottom centre is my Advantage-camouflaged boonie hat.
  • Sitting on the boonie hat is a plastic bag carrying a small fire kit. This has two butane lighters, two nightlights, a 35mm film container filled with Vaseline-soaked cotton wool and a Fresnel lens.
  • Below the fire kit and to the left is an ACU-patterned headover which can serve various roles including as warm headgear.
  • Bottom right is a one-litre Playtpus waterbottle. Sitting on it are a shoelace, hank of general purpose string, hank of green paracord and some braided fishing line wrapped around a piece of plastic (yoghurt carton).
  • Not shown: two supermarket carrier bags. I wear photochromic spectacles. If you do not, a pair of cheap sunglasses may be a prudent addition.

The whole collection packs into a draw-cord bag, as shown. Note snap-link added to one carrying cord. This bag is lined with another plastic bag to provide better water resistance. The headover is folded into a pouch and used to contain some of the smaller items. This pouch, in turn, is placed inside the boonie hat. Most of the pack contents are soft and crushable so no great genius at packing is really needed. Put the blanket in first and add the other contents. Put your water-bottle away from your back and ensure your poncho rides near the top of your bag.
Packed, but without water, the soft core bag weighs about 1.3 kg. The volume of water I will carry and which water-bottle I will carry will vary with climate and anticipated conditions.
The soft core pack is easily stuffed into a larger bag, immediately adding a collection of very useful items. On its own, it is a good bag to have for trips where you do not want to be bothered by a bag. It is light and low-density, and makes a pretty good pillow.
A quick glance inside the first aid kit. Items in this kit are consumed in preference to those in the skin-level EDC. Vaseline is good for chapped lips and other ailments.
The soft core bag probably has more cordage than it needs, but I had some hanks already made up. This is a nice example of paracord carried using hojo-jitsu configuration.
