I would have expected a larger crater for Tolkien..


Thats the manual for an older configuration, not the one that flew to the moon.The CM hatch has the pre Apollo 1 fire design, and the booster is a Saturn 1B, not a Saturn 5. Does anybody know if something like this ist available for later configurations?


You seem to know a lot about Apollo - could you share some good sources to dive into on this please? I've always been interested so I thought of researching this in a lot more detail recently.


Depending how deep you want to dive into this rabbit-hole:

-How Apollo flew to the Moon: https://amzn.eu/d/1QtsN1D Covers in my opinion all aspects of the Apollo/Saturn programme, including design, technology, procedures and a lot of history as well. A must read if you are interested in such things

-Moon Lander https://amzn.eu/d/bI3wpt7 Memoire of Thomas Kelly the chief engineer for the Lunar Lander. Gives great insights of the technical and management challenges while desiging the first "true" spaceship. Highly recommendet!

-Digital Apollo: https://amzn.eu/d/0KigTU9 Focuses on software development (actually an afterthought to hardware development) for the Command Module and the Moon Lander and on the important aspect how much controll should be given to the astronauts against automatic systems. Includes a very detailed analysis of the software alarms that almost compromised the first moon landing.

-Failure Is Not An Option: https://amzn.eu/d/ix6CWnq The memoir of the Gene Kranz, the tough, no bullshit flight controller pictured in the Apollo 13 movie. Kranz was a key player in the manned space program for decades. Here we learn that almost each moon mission had critical moments and had to be saved by the teams at mission controll and the astronauts.

Other interesting books: -Moon Launch: https://amzn.eu/d/1Z6U5f6 on Saturn Apollo Launch Operations -Sunburst and Apollo: https://amzn.eu/d/2ms3IW8 a personal memoire of one of the software designers for the LM computer

Hope there is something interesting for you in the list.


Thank you very much for the recommendations! I'll probably end up reading top to bottom (or definitely try!)


I can not recommend this enough, a must have if you like Escher's Art and are in weird geometric stuff.

Beware of "online QR code services", all of them insert some spam redirectons in the QR code. After trying a dozen founds from Google, I finally found a decent one from a german university.


I made this one so I'm pretty sure it doesn't do that — but you just got me thinking of all the QR codes on tombstones and inked into people's skin that probably redirect to a pay day loan website or something.

The trick is to use whatever that is built into the system you are using. On iOS I use the Shortcuts app to create an action to generate QR codes. On desktop I just use Chrome's built-in QR code generator right from the address bar.

Assuming you already trust your OS and your browser, this means you do not need to trust any additional party for this simple task.


Nice reference to the Musical Youth Song of 1982!


Cheers. Only waited 40+ years for it.


The most interesting thing is the Force/Displacement curve. It shows some plastic deformation even after the breaking point, which is unusual for „hard“ Materials. May this just be some gloryfied Epoxy with wood as filler?


That stress/strain curve in the Cell Matter "Graphical Abstract" is garbage past the point of peak stress. If it's tested in their double shear jig as shown, once it displaces significantly (> radius of the nail) the force is more the pull-out force, basically just the friction between the hole and the nail surface. Or, the nail might just be digging an oblong hole in the shear jig. It's maybe interesting, but a regular stress/strain setup is better to lead with.

The Nature article has some normal stress/strain curves which show brittle failure https://www.nature.com/articles/nature25476/figures/6


It appears they are relying on the hydrogen bonding in the cellulose after lignin removal, so it should be >50% wood, i.e. not an epoxy with wood filler.
