The problem is when AP-writers and employees of the company use it that way, though.

Oh, don't get me started. Strange Aeons is guilty of Charm Person at the dinner table (you know, AP authors, bards and Spellsong have existed for quite a while now, because of EXACTLY THAT ISSUE). Every AP assumes that the bad guys, on hearing the PCs, will have all the time in the world to cast all their buffs, when the PCs will hear the bad guys casting as well, and likely come a-runnin'.

Overall, you put it very well:
- If the PCs want something to work a certain way, they have to accept that it will work exactly the same way for the bad guys, no arguments allowed. That usually nips such nonsense in the bud. ("The succubus rolled a 42 on her Diplomacy. You are now her willing slave. No save.")

- If the AP wants something to work a certain way, it works exactly the same way for the PCs. This can entirely break APs. So my bad guys are frequently caught unbuffed, which makes those buff-included stat blocks very annoying. I don't know why it's so much harder to debuff than to buff, but it is.

I live by a simple: "If the PCs can do it, the bad guys can do it. And vice versa" mantra.

You'd be amazed how fast players back down when you say, "OK, I'll allow it. But it means my bad guys get to do it, too."

Things I've learned:

Hollowing out eggs for pisanki is damned difficult.
I bought a pack of 18 eggs, figuring that over the course of the next week, I could use them a few at a time and then wash and dry them.
I remembered watching my aunt do it and I'd read internet tutorials, so how hard could it be?
My current success rate is 1/4.
Also, after going through three different tools, the orchid stake (not pointy but very small and hard) worked better than the wider tools with sharp points.
You can make pisanki out of hard-boiled eggs and keep them in the fridge, and eat them as you want.

No, I absolutely cannot.

Because the only thing worse than the taste of hard-boiled eggs is the smell of hard-boiled eggs.
I detest eggs in every form except quiche (and only then if the bacon and mushrooms are sufficiently strong), souffle and meringue.

If you dislocate a hip can you wiggle yourself back, or what is the procedure?

*gets dressed*

I've just gotten really good at falling. Not kidding. I'm amazing at falling without hurting myself. Even if I've only got a second I can usually get close enough to the ground. But bathrooms are not easy for that even for me. Not really anything I can do about it. Everything is just really close together. Best I can do is try and brace myself against stuff so I don't hit my head.

And yes, that's basically it. I can twist and pop and wriggle joints back into position quite well. Sometimes I need some help. It's really hard to put back a dislocated shoulder by yourself. I have special stretches to pop a hip back into place. Or a knee, thumb, wrist, etc. Ribs are bad though. It's really hard to twist around well enough to put a rib back. I have to go to the chiropractor for that. So dislocated ribs are something I dread because the longer something stays out of place the worse it hurts. Anyhow, if you ever meet me in real life and it seems like I'm wriggling around a lot, I'm just trying to put my joints back where they're supposed to go. ^.^

if you could find a way to weaponize that, you would be an amazing assassin.

When I mentioned to Teensy Valeros that I. Major would be going to see the movie in costume, he insisted on the errand.

So, for reasons lost in the annals of time, Impus Major was unfortunate enough to see Gnomeo and Juliet years ago. When he heard that they were coming out with Sherlock Gnome, he became obsessed with seeing it, on opening day, dressed as a gnome.

Yep. Definitely my son.

So Teensy Valeros got Gnomeo in a Burger King Happy Meal equivalent. He decided that Impus Major needed to borrow him. So tonight, mid-tactical discussion, there was a quiet knock at the door. Mr. Stereotype got the door and was speechless; teenagers just don't know how to deal with young kids. Teensy Valeros held up Gnomeo and said, "This is for Impus Major."
Impus Major came clambering over the furniture (because it's what he does) and his face exploded in a HUUUUUUUUUGE grin!
"Is that for me?"
"Yes!"
"Is it mine?"
"No, it's mine. But you can have it for the movie."

Man, Impus Major was ludicrously happy. Now he's going to go to the movie in costume and with a little Gnomeo.

Yeah, I'm not going.

I'm too serious to go anywhere dressed up as any character. I know the word is cosplay, but I'm way too self conscious to do it. I actually admire people who can pull it off.

It's really not a matter of pulling it off, for me.

My daughter and I are both ridiculously shy and introverted.

As in, my husband will invite thirty people over to our house for some random occasion, I will cook, and then she and I will sit at the top of the staircase listening to the party together and crying because it's just too damned many people we don't know to actually go downstairs and join in the "fun".

But we both love to cosplay, because it gives us a way to be in a large group of people without being scared. I'm madly trying to finish the costume she's asked me to make for her for...

worry not. If I visit, it will just be me.

Tonight "chaperoning season" starts in earnest. And my hair is even grown out! (Not so bad in NoCal, but showing up at Crenshaw in a mohawk just might get taken the wrong way...)

So it's kind of fun:

  • March 22: Pre-trip chaperone-only meeting
  • March 28: Pre-trip "reassure the parents" chaperone meeting. I have been forbidden from wearing lederhosen without the mohawk, and she made the grow the mohawk out, so what am I gonna do?
  • April 4: Rent the massive minivan that may or may not take kids down, do Costco runs, other store runs, etc., etc.
  • April 5: Actually go on the trip

  • Last time the middle school and high school trips were two weekends in a row. Fortunately, since this nearly killed all of her chaperones, the choir director separated them by a couple of weeks, so I'm free 'til the end of April/beginning of May.

    I'll just say that, though I love me some Kurgestatz (I will never spell that name correctly, so I'm not trying), this was not one of their better videos, because it heavily obfuscated some very real and genuinely serious issues.

    The Industrial Revolution was, and continues to be, awesome, but it is not the "Everything is Different Forever and Nothing Can Go Wrong with More" they paint it to be in said video - point in fact, they are entirely wrong in their implication (though not statement) that now we have free, infinite resources...

    The same assumption that video makes is also the assumption behind the post-scarcity non-economy of the Federation in Star Trek.

    Great, so you can turn energy into matter. That means your limiting factors are your supply of energy and the degree to which you can replicate something. Wait, you're using an antimatter reaction? That is the absolute worst of the nuclear reactions for energy generation; you're spending more energy just to create/store the antimatter than you get from it. It's the same reason why hydrogen fuel cells are a stupid idea: You're spending a lot of energy to just temporarily store energy, when you could devote half to a third of that energy to have a primary energy generation unit inside the vehicle itself. It's just wasteful.

    Also, let's not talk about the waste issue. Star Trek aptly demonstrates why the entire way the Federation treats power generation is worthy of a Darwin Award.

    This probably explains why the shows and movies drop hints that the "post-scarcity non-economy" of the Federation is probably mostly propaganda and that they're far worse off than even Medieval Europe was.

    Producing antimatter is costly but it's very efficient practical way of storing significant amount of energy because of its energy density when you consider need for extreme spike of energy consumption. Yes, you could have a generator producing a steady supply of energy that would be more effective in long term, but it would be challenging to have generator producing comparable amount of energy in short time. It can also be viable method of energy storage when you have access to a big energy source that emits large amount of energy independently of your actions (say, a star) and majority of that energy will be wasted to the space unless you build a Dyson swarm of small solar-powered cyclotrons that will use captured energy to generate anti-matter. Once you have that level of engineering producing magnetic bottles to store it isn't really a big issue.

    Star Trek goes around the issue of enormous costs of generating antimatter by using fictional substance Elerium 115 dilithium, which generates antiparticles in certain conditions. Of course it simply pushes the problem of scarcity to access to dilithium - which acts as a interspecies currency for races that don't use singularities for their power needs.

    I wanted to go post in the fly skill thread that if you get a fly speed, you gain fly as a class skill, but since your fly speed is temporary and you can't gain skills as class skills temporarily, you can't gain fly as a class skill. But it was nearly midnight and I was trying to find rules to support that viewpoint and came up blank. Generally people don't talk much about it.

    Anyway, I'm happy it's Friday! Though today looks like a busy day...

    And I'm already tired at the start of it. What the heck, Mort?!

    Gaining Fly as a class skill only gives you the +3 bonus if you have a rank in it. Gaining a fly speed gives you a maneuverability bonus, which is not gaining a class skill.

Of course it simply pushes the problem of scarcity to access to dilithium - which acts as a interspecies currency for races that don't use singularities for their power needs.

    Dilithium doesn't generate antimatter. It regulates the matter-antimatter reaction to produce a stable and controllable reaction. That's why the dilithium is inserted into the reactor and not the antimatter storage compartment. Without the dilithium, the warp reactor would be prone to randomly exploding.

    Star Fleet doesn't have the technology for a true Dyson Sphere for energy production. The matter-antimatter reactors are their most powerful source of energy, and they lack the magnetic bottle technology necessary to keep that reaction stable.

    The fact they ration energy for civilians even during peacetime suggests the Federation has some serious power generation problems, so the idea they have a power source that can easily supply that antimatter is rather doubtful.

    Unless you have some massively advanced magnetic bottle technology, antimatter is at best an extremely short-term energy storage method. It tends to turn back to matter, so you're going to have a matter-antimatter reaction inside your storage chamber at some point unless you spend a lot of energy to keep it as antimatter. You need a constant power source for this, one capable of supplying a high energy load for an extended period of time. Overall, storing it for points when you need bursts of energy makes no sense because you'll spend far more energy to preserve that burst than you'll ever use for the burst itself. It would be easier to simply use volatile chemical compound, which can provide the same benefit with some higher material usage for much less energy invested.

    This is why antimatter is very useful for weaponry, but not for power generation.

    Given the Federation has trouble dealing with a normal reaction, the idea they can prevent antimatter from turning back into matter becomes well outside their demonstrated technological capacity related to the substance.

    "Creatures with a fly speed treat the Fly skill as a class skill. A creature with a natural fly speed receives a bonus (or penalty) on Fly skill checks depending on its maneuverability."

    Fly spell counts for the maneuverability. Does that mean when fly is cast on you, you always gain fly as a class skill?

    Also we'll assume you have ranks in the fly skill, since you've been flying.

    The difficulty is that you're treating the rules as a legal treatise.

    Pretend, for a moment, that the authors were humans, not lawyers.

    STATEMENT 1: "We need to make sure that flying creatures can, y'know, actually fly and not plummet. Even the low-CR ones."

    PRD wrote:

    Oops. The writer messed up. Is it natural flight, or is it all flight? So they tried to clear things up in the FAQ with one of most convoluted clarifications I've ever seen attempted:

    FAQ wrote:
    Despite the fact that the Fly skill mentions that bonuses and penalties from maneuverability apply to creatures with natural fly speeds, they apply for any fly speed. If they didn’t apply to creatures that gained flight artificially or through magic, then those maneuverabilities (like the listed good maneuverability for the fly spell) would have no game effect.

    OK, so we accidentally used the word "natural" in the second original sentence. Was it supposed to be in the first sentence?

    Your honor, I move that this rule be entirely abolished from the game!

    Or we stop treating the rules like as if they were written by lawyers, and we try to figure out what they meant.

    They say that the Fly spell gives you Good maneuverability. I assume they say this because they want to give you the +4. They do not say that Fly is suddenly a class skill for you. I assume that they don't say this because they agreed that this would be silly.

    So Fly adds 4 + 1/2 CL to your Fly skill. I'm happy, and I don't break my brain trying to parse contradictions.

    Which is completely unnecessary. Just build a few millions of satellites with high-efficiency solar panels - exceeding modern conversion rations but easily within reach of civilization that can easily order molecules via replicators. They could be used to power various devices and robotic factories.

    Neither Federation nor other civilizations of Star Trek (and most other SF settings) don't do that because of creators' fiat.

    Two words: artificial gravity. If you can generate adjustable artificial gravity you are probably capable of trapping matter or antimatter. Its abundance implies that it doesn't use a lot of energy. Its one of many cases of the show's internal inconsistencies.

    Quote:

    Any sources for that? I find no information about antimatter simply reverting into matter. CERN complains about the issues of trapping the antimatter before it finally annihilates with mater but it's engineering issue of keeping it trapped with the current technology.

    Quote:

    Chemical compound? Excuse me? You surely are joking now...

    Energy comparisons:

    It won't provide nowhere nearly the same benefit. Chemical compounds have energy in ranges up to 50 MJ/kilogram (142 for things compressed hydrogen, but it has much lower density so it has a little over 9 MJ in a liter as opposed to 37 MJ/L for kerosene)...

    In comparison, nuclear decay has energy of 500-2000 thousands of MJ per kilogram.
    Controlled nuclear fission has energy of 80 million MJ per kilogram of active substance.
    Nuclear fission explosion is approximately 150 million MJ per kilogram of active substance.
    Deuterium-tritium fusion is 500 million MJ per kilogram...

    10 millions times the energy stored in chemical compounds. 7 orders of magnitude.

    ...

    Matter/Antimatter is almost 90 billions MJ per kilogram. 9 orders of magnitude.

    Antimatter might require enormous amount of energy to produce, but on a spaceship where mass and volume are at premium, its the best known way of containing energy even if 90% of space occupied by "antimatter battery" is actually the casing and containment unit that consumes 90% of energy produced from M/A reaction.

    I love that you guys are having a super-nice/friendly nerd fight on the same day that I'm listening to the glorious Isaac Arthur about Teleportation.

    Life is good sometimes.

    Which is completely unnecessary. Just build a few millions of satellites with high-efficiency solar panels - exceeding modern conversion rations but easily within reach of civilization that can easily order molecules via replicators. They could be used to power various devices and robotic factories.

    Neither Federation nor other civilizations of Star Trek (and most other SF settings) don't do that because of creators' fiat.

    The Federation doesn't do it because the Federation doesn't use satellites much. Haven't you noticed how, in their depictions of Earth and various Federation worlds, the worlds are missing the rings of satellites that any world of sufficient advancement, like modern Earth, would have?

    It's not that they don't have the capacity to produce the equipment. It's that they've lost the basic technology to make a regular satellite. And if they can't make one to easily orbit Earth, making one to orbit a star is definitely out of the question.

    Gravity in the Star Trek universe is a particle. The artificial gravity is generated by low-energy particle emitters. Building a low-energy particle emitter is a vastly different technology from building an advanced magnetic bottle.

    Try here. The discovery that matter-antimatter transformation tends to favor matter in at least some mesons was made in the 1960s. These mesons, in turn, make up the bigger particles that eventually become atoms.

    I'm not joking. And if the choice is between "strap more fuel canisters onto the ship" or "risk it randomly exploding," people are going to choose the canisters.

    The energy composition of antimatter comes with a risk that is simply too great under any power generation scenario where it would have a chance of being beneficial. Under the scenario in which you're trying to store it for energy, you're basically having to spend constant energy to keep it as antimatter and keep it from touching something and causing an explosion.

    But this has no relevance to Star Trek. As John noted, Star Trek ships don't store antimatter; they spend massive amounts of energy to create it on the fly using standard fusion reactors. That means their energy limit is dictated by how much they can get out of those fusion reactors as much as it is by the dilithium availability.

    They don't have the technology to store antimatter. That much is evident just from looking both at their difficulties in using it and the fact they make no effort to store it after creating it.

    I've got the first half of my parent-teacher conferences tomorrow and I'm only 40% done with writing up my reports for the parents, and I picked up a bag of jelly beans to give myself a nice sugar high for the up-until-two-a.m. evening of jollity ahead of me, and I accidentally got the fruit flavored beans instead of the spice flavors.
    You know, for those of us who actually like clove or horehound flavored candy.
    I am not amused.

    Uh, it doesn't make any shred of sense...

    If you can build a starship, you can build a satellite, period, if you can't build a satellite you wouldn't be able to build a starship. To put it bluntly, a satellite is anything put at the right speed around a celestial body so it retains somewhat stable orbit. If one knows grade-school math, one make the required calculations using simple calculator (as Apollo-era computers had less computing power than modern... well, anything). If you can't make those equations, you wouldn't be able to launch a starship anyway.

    Absolutely everything that is needed to build a satellite is available to Federation and actively used: drives that can launch object into space, maneuver drives to correct, math to put it in the right orbit.

    BTW: Federation explicitly does use satellites: example 1.

    If you can manipulate gravity you DON'T need magnetic bottle - you simply suspend the mass you want to isolate in a properly shaped field of gravity (or lack of). While the general scientific expectation is that antimatter is subject to normal gravity interaction, there is some chance that will instead react in opposite way (which will be easy to work with anyway as it would repel normal matter in such situation) or with different magnitude (which will be workable around too with the right adjustments).

    Try here.

    The article speaks about mesons and antimesons, which are already highly unstable non-baryonic particles with a short lifetime anyway. It doesn't say anything about antiprotons/positrons decaying into protons/electrons.

    If anyone would confirm that antiprotons have a limited lifespan after which it would decay into matter, then it would be big news, Nobel prize-big.

    Quote:

    No, they don't. Mesons are separate subfamily of particles from those that build atoms. Electrons and protons are stable particles. Neutrons can decay into protons (and some kind of neutrino or anitineutrino). Antiprotons and positrons are expected to behave rather like protons and electrons.

    Elementary Physics:
    Atoms are built out of electrons, protons, and neutrons. The last two belong to a group known as "baryons" and each is composed of three quarks (generally in groups where two are the same and the third is different). The exact set of quarks determine what particle we have. Antiprotons and antineutrons are built out of three antiquarks each.

    Mesons are separate group of particles composed of one quark and one antiquark.

    Mesons and baryons together form bigger group known as hadrons - particles that are built out of quarks unlike leptons, which do not contain quarks (and include electrons and positrons).

    I uh.. Shouldn't look too closely at physics. It will eat the thoughts out of my head.

    Anyway I was having a headache earlier but after I did a body combat session in the gym(didn't want to let my regular gym class buddy down), it went away!

    Let's hope it doesnt come back.

    What the heck? I went to check out what class I am and turned out as a bard.

    Let me tell you I have nothing in common with that sap Elan from order of the stick.

    And I did not dump int!

    I dread to take that test. I would probably be a galley slave or a ditch digger.
