Talk about Pot calling Kettle. Women; just can't keep their hands to themselves.

@iNow You might be interested in a plunging track saw for cutting boards. Here's a video about them: You can knock a support frame up to saw on, like the table top in the video, and lay it down on the floor and then stack it up against a wall when you aren't using it. I don't have space for a work bench so portability is important to me. You can cut sections out in the middle of boards because it's plunging as well... just hand saw the corners I've just bought a fairly simple one with 1m track. It doesn't do angles but can set depth. It was £65($75) delivered... bargain! This one has 30mm cut depth and light enough to be used one handed. Ideally, you want a track length equal to the standard width of boards; 4ft or 1400mm here. I have a couple of little projects involving cutting up boards and this seems a good cost-friendly, portable solution for a hobbyist. This is my saw: http://www.rutlands.co.uk/sp+woodworking-power-tools-machinery-plunge-saws-plunge-cut-saw-with-1m-track-rutlands+xt3510

There's a few of us silvery ones here so you won't be alone. I'm a bit too young for Gemini missions but remember Apollo. Welcome to the forum.

Hand skills are always useful for in situ modifications.

A Japanese Kiridashi knife is designed for that job. It is composed of a hard thin plate, which holds the sharp edge, laminated to a softer main section for strength. A jack plane or bigger will get across the undulations on longer pieces. Also, look into Japanese pullsaws as well because they make hand sawing effortless with extremely clean edges. By pulling the thin blade always stays rigid in the cutting direction and the kerf is much thinner than with a push saw. I'm a big fan of Japanese tools. Here's an article on them. The Shark saws mentioned are great and I'm SO glad I just found them again just now after ages trying to remember the name. https://www.infinitytools.com/blog/2016/05/24/introducing-shark-and-japanese-style-pull-saws/

Conquest of Paradise - Vangelis

Yes, I''ve watched it a few times too. He's got some serious nerves and talent to behave the way he does and do that stuff that as well. Edit: Cocked up. Replying to Koti. Yes, there is a hippy element in his routine.

Reggie Watts disorients you in the most entertaining way.

Yes, having knowledge and being able to usefully play with it are two different things.

This sort of stuff used to drive me nuts but it sounds ok now.

What constitutes 'reality' is the result of intersubjective consensus and those that have a different internal mental construct from that consensus are considered to be outliers.

Definitely. it would be useful to you as well in consolidating what you've learnt in communication terms as well as the physics. i think it would be good if you aim for the same sort of audience and in the spirit that Sean did in that video but in written form. I'm sure you are quite capable of writing for a mathematically-capable audience as well but I think they are probably well catered for.

Perhaps you might write something in durable form, some time, so that others may appreciate your clarity. All other other treatments of this subject I've seen require quite extensive prior knowledge. You and Sean Carroll's video have made it a lot easier for us neophytes. I would call it "The Neophytes Guide to Fields". Put me down for a copy. Volume with nothing in it is nothing. It is defined by what's in it or the space it occupies. You can't have 'length' without something having length. It's a property of things. 'Space' has something in it, be it only fields.

Volume is defined by whatever occupies it. Whatever occupies it defines the boundary. It is a parameter and does not exist by itself.

It's all good. You do a fine job introducing people to the idea of fields in an accessible way.

Yes, I understand that not all extend, potentially, infinitely.

Up to now, space has not been quantised so we can only assume it's volume. Scientists did an experiment that went on the basis that if space was granular, red frequencies would travel faster than blue ones since their velocity might be impeded less because of the granularity. The distances required went to billions of light years but both ends of the spectrum arrived, effectively, at the same time.

But - I assert - fields permeate the whole universe; gravity/spacetime extends everywhere.
