Which, let's be honest. Is just as cool as Skynet.

I'll be the one that designs the screaming VTOL attack drones that land on your head and lop it off so it can take your brain in for forced uploading to the master computer.

How would I determine the apparent magnitude of a star roughly 65 AU away, with a luminosity of 0.45, diameter of 1.2 M km, and temperature of 4839K?

More or less I want to determine whether or not this would be bright like a full moon, or just bright like Venus or Jupiter.

Picture related.

Sup /sci/

I'm using Universe Sandbox to create a solar system.

It is currently a trinary system with one Main Sequence star with slightly more mass than our sun, and two dwarf stars in a binary orbit around the primary. In orbit around the binary stars is a single gas giant sitting around 7 Jupiter masses; the temperature range for this gas giant is 40*C to 120*C, apoapsis and periapsis respectively.

I'm going to place a binary planetary pair at 1.03 and 0.97 Earth masses between the main sequence primary and binary dwarfs and in the habitable zone; beyond that, this solar system is your canvas. Feel free to suggest new planets, moons, orbital types and names. Nothing above 7 Jupiter masses.

Not the OP, obviously.

But I've always viewed the human consciousness as the 'program' running on the hardware that is our brain.

Doesn't mean you can't learn through Khan Academy.

Personally, I use it as a supplement. Khan Academy, Wolfram Alpha and OpenStudy are all about as helpful as having a tutor on-hand whenever you want.

>> No.4116784 [View]

I signed up for this the moment I could, especially considering I'll be taking a Spanish course in my next semester.

Stuff like this and Khanacademy... it's like I don't even need university anymore!

>And apparently Russias space agency has no way of tracking its own probes, so they are having to ask regular people in South America and NASA+ESA to track it for them which makes things difficult.

This is true of /all/ the space agencies.

Nobody has listening stations built all around the world, even the US has giant blind spots.

So we talk to each other and share info.

They thought a couple days at first.

Then they checked out how long the batteries would last the way it was going and said it'd be good for about two weeks.

>I suspect it comes down to the underfunding of russia's space program, 100 -200 isn't much at all really.

Not a problem with funding, really. Just a typical issue that can crop up. In this situation the probe did not properly orient, and they're not sure if that's because of a software malfunction, or a hardware malfunction. If it's software, they can hopefully upload new commands to the probe and fix it.

Hardware issue might be more problematic.

IIRC, last stage went into orbit with both probes (china has one piggybacking on the launch)

But it didn't orient correctly, so it entered standby mode.

Engineers have about two weeks to figure out how to get it facing the right direction before it runs out of power.

Probe is in orbit tovarisch.

Venus. It's the most earth-like planet in our solar system, aside from Earth itself.

I feel like I'm just slow.

Not stupid, just slow. Like, other people can figure shit out in a few seconds, but I need to stop and actually process for a minute. I'll get the right answer, just not quickly.

Not realistically enforceable. The wiki article should already cover that.

That's because it takes time for your receptors to 'reset'.

You can also 'see' light by pushing on your eyeball. In actuality, there is no light, the pressure is simply triggering photoreceptors.

It's statutory rape.

She had sex with someone who is underage. Which is considered statutory rape.

It doesn't matter if he liked it or didn't like it. That isn't even a consideration. She had sex with an underage boy, it is therefore statutory rape.

I know tons of people who learned English by playing videogames.

And for myself - Europa Universalis and the Total War games have been instrumental in developing my understanding of history. Far moreso than a decade of school even came close to.

Solution: Trillion km thick receiver

Or find out how to interact with Neutrinos reliably. I bet you could win a nobel prize for that.
