To roll a dice I should first consider the "time" axis as something external to the Universe. But as the Universe (or the ultimate ensemble) by definition includes everything (including any possible "time" axes), I can't do a roll, I can just have all possible roll results at once. And any result, like any action in the Universe, "appears" just when you reduce the Universe scope at least by one coordinate axis, which you treat as "time".

Delay Posted August 11, 2019 Share Posted August 11, 2019 In what way is that different from stating the universe is not predestined? Every event has a huge list of possible outcomes. The universe "decides" on one of them. Given that other options have existed - after all we can abstract them - I don't get the difference between a randomly picked, predetermined result and a perfectly random one.

Just a multiple predestination with technically infinite number of cases. 2 hours ago, Delay said: Every event has a huge list of possible outcomes. Like any chess board cell has multiple possible "next cell"'s. 2 hours ago, Delay said: The universe "decides" on one of them. Decision is an action, so it also requires "before"/"after" axis, at least one bit long. So, the Universe can't "decide", in only "includes", all of them. 2 hours ago, Delay said: I don't get the difference between a randomly picked, predetermined result and a perfectly random one. When you run a computer random generator, you get just a pseudo-random. When you throw a dice, its result depends on the initial atoms positions and applied forces, it's not a real random. So, a "random" is just a "depending on uncertain set of values". Quote Link to comment Share on other sites More sharing options...
Lisias Posted August 11, 2019 Share Posted August 11, 2019 3 hours ago, Delay said: How is it predestined if the result is only determinable at the moment of observation? Because we limited the possible outcomes to two: or the cat is alive, or the cat is dead. Both are the predestined outcomes of the cat inside the box. Since the box is closed and its inside is unobservable, at a given instant, the can be alive or can be dead - and by practical meanings, they can be both. The cat is inside the box, out of our reach. But this doesn't means that the cat is, effectively, dead and alive at the same time. It's just means that for us, outside of the box, it doesn't really matter - as long we don't open the box.

kerbiloid Posted August 15, 2019 Share Posted August 15, 2019 (On this morning emergency landing of A321 near Moscow. A pack of Angry Birds hit both engines after takeoff, so it has landed on a field next to the airfield as a glider with gears up to slide along. No lethal casualties.) As a plane should slide when landing outside of runway, so they keep gears up, I guess all passenger airplane designs must have gear nacelles to be used as skids. This is both safer and more beautiful. Spoiler Also they can be equipped with warmed extra passenger seats. Quote Link to comment Share on other sites More sharing options...
Superfluous J Posted August 15, 2019 Share Posted August 15, 2019 So let's say you're unlucky enough to have snipers aiming at you with laser sights. How unlucky would you have to be - as in how many snipers would need to be aiming at you at the same time - for you to feel the warmth from the lasers?

How unlucky would you have to be - as in how many snipers would need to be aiming at you at the same time - for you to feel the warmth from the lasers? Depends a lot on the type of laser. And then on the color (absorption) of the skin or whatever surface they hit. But generally speaking, the warmth of one regular laser pointer on your skin is way way below the "detection limit" of our skin. I imagine even if you combine a bunch of them it would be hard to feel it. Especially if you consider that those dots would not be stable and move and twitch all over the place. Aiming them at the exact same spot and keeping them there is only possible in an experimental setup where everything is fixed down nicely. With that said, who knows what kind of super lasers are out there. I could think of IR beams that would only be visible if you wear the right goggles, and such beams would heat up materials way more than your standard red pointer does. cheers Quote Link to comment Share on other sites More sharing options...

For as soon as I noted the dot, there would be a warm trickle down my leg from my cowardly bladder. I would notice the dot purely because my cat would be attached to my face in pursuit of it.

kerbiloid Posted August 15, 2019 Share Posted August 15, 2019 (edited) They say, most of laser sights have 50 mW power. So, probably you won't feel it, as a sniper would be probably aiming not you, but a thing next to you which you can't see, with his sight adjusted to make the rifle hit the point 30 cm down from the spot, or something like that. Upd. Unless you have a similar cat. Edited August 15, 2019 by kerbiloid Quote Link to comment Share on other sites More sharing options...
TheSaint Posted August 15, 2019 Share Posted August 15, 2019 Reality check: Despite what you see in the movies, most military personnel IRL don't use laser sighting devices. The one exception is at night they will use infrared laser sights, like the AN/PEQ-2 or the AN/PEQ-15, which are only visible if you are using night vision gear. (Because trying to sight through a normal scope or iron sights while you're wearing NVG is a PITK.) Snipers would never use a laser sight, because snipers are shooting long distance, multiple hundreds of yards/meters. All a laser sight would tell them is their point of aim, which they can already see through their scope. Their point of impact will be inches/centimeters below that. They have to calculate the point of impact in their head based on range, azimuth, bullet weight and velocity, air pressure, wind, etc, to correct their point of aim to actually hit the target. (Snipers are an excellent example of weaponized math.) If you want to see something really nifty, check out the Sig BDX system. You have a laser rangefinder that measures the range and azimuth to the target, it feeds that information via Bluetooth to an app on your phone (where you have pre-entered your bullet weight and velocity, altitude, and other data), which then calculates your corrected point of aim and projects it into the riflescope via an illuminated dot. But, sorry, the laser pulse only lasts a fraction of a second, still no heating. Quote Link to comment Share on other sites More sharing options...

More like an anti-lazy-hunter device. Real snipers, who have their lives, other's lives, and their missions depending on their accuracy, would never use a system like BDX. Because: Just when you're ready to take that perfect shot, <ding> <ding> "Searching for connection..." I said it was nifty, I didn't say I would actually shell out the money and try to use it.

bootsam Posted August 16, 2019 Share Posted August 16, 2019 My thoughts whilst in the shower consists of this - of all the bottles of product on the shelf, which one is my shampoo and which one is my shower gel. It has become akin to looking for the proverbial needle in a wifeys product haystack. It is further excarabated when it comes to looking for my deoderant shortly afterwards in the cabinet. I have one bottle of shampoo, one bottle of gel and one deoderant. It has become something of an early morning supermarket sweep quiz show. All the shelves are full as is the cabinet, of a vast array of mysterious and baffling products. I used one of her products once and was promptly told off and informed of its cost. What?! Youve got to be kidding me. It's shampoo, how can it possibly cost that much? I get 'that look' and decide discretion is my best tact. Plus, why do I always get the slightly damp towel and why is it always outside arms reach? Dont get me started on the wardrobe. 50/50 she said. Yeah, tis more like 90/10...
