Want to be a time traveller? Now you can be!
PakledHostage replied to kiwi1960's topic in Science & Spaceflight
Then what good is your avatar? I thought you said you were a time lord? -
I don't know about Buenos Aires, but Argentina has some awesome conditions for gliding. The world altitude record for sailplanes was set there, and the Perlan Project hopes to reach 90,000 feet there.

Sorry. Turns out that I was confusing you with someone else. I should have checked my facts rather than relied upon my memory. Mea culpa.
-
Why do you pick only that example? There are plenty more examples of "facts" that you have either quoted out of context or that are outright wrong. A cherry picked example does not make a counterargument. I may have been a bit flipant in one or two posts and I am sorry if I offended you. It was clear from the beginning what your bias is, and I am only pushing your buttons to try to draw you out from behind your veil. You've expressed "denialist" views in climate change denial threads on this forum in the past and readers of this thread should be aware of that.

There's also NASA's Eyes on the Solar System program that is free to download. It has the added feature that it shows you where lots of satellites and all of the robotic probes are currently located. It's interface is a lot like KSP's map view.

No, the difference is that you seem to be playing a subtle style of politics couched as some sort of rational scientific skepticism. You are clearly arguing from a biased position. Your posts are full of misinformation and misquoted evidence and now you're even hinting at an argument from authority. In climate change debate circles, your style would be called "concern trolling". You raise "concerns" that sound reasonable to the gullible and uneducated so that you can spread doubt. Don't kid yourself. You're absolutely playing politics and it isn't new or as subtle as you think. You see those underhanded tactics in politics all the time.

I was able to capture Jupiter, Venus, Ganymede and Europa (at least) in several images shot through a 300 mm lens mounted on a DSLR. Callisto and Io may be there too but I'll have to look for them after I download the images to my computer. I'll post them here tomorrow. Here's one of the photos. Frida Space's composition is better for sure, but I didn't have a decent foreground for my photo so I went for a zoomed in shot. I think I would have needed a graduated ND filter to block some of the light from Venus if I were to succeed at exposing them both more uniformly. It was also complicated because I have a crappy tripod and I don't have a tracking mount so exposures had to be short (i.e. I had to use high ISO and large aperture). Venus is way over exposed and Jupiter just looks like a white blob, but you can see the four Galilean moons around Jupiter:

Well I guess that's a good reason then. Forgive my skepticism. There's just too much Manley fanboyism around here. A couple of sentences about why we should want to watch the video would have helped.
-
And? Should we be interested because he's Scott Manley! Or because he has access to information that we don't have access to?
-
You're back! I noticed you'd gone away for a day or so. Glad to see you're back here now, casting doubt on global warming. All is right again in my world.

No kidding, eh? What always gets me about these discissions is that climate change deniers are basically conspiracy theorists. A guy claims that his instrument can't measure temperature with the requisite accuracy and suggests that no instruments can, therefore the science is bogus... But the science is peer reviewed. If what he says about measuring temperature was true, wouldn't an expert in metrology have pointed it out already, thereby tossing the whole idea of climate change into the trash bin? Authoritatively and definitively disproving an entire field of research's fundamental premis would seem to be an excellent way to make a name for one's self, wouldn't it? If there was any real doubt, wouldn't the brightest minds be all over attempting to disprove anthropogenic climate change? It is impossible to believe that no reputable scientists would pursue any research that goes against the established paradigm without also believing that there exists a conspiracy motivating that resistance. Scientists have egos just like everyone else. Some even more so. Give them a chance to turn the scientific world upside down and they'll take it, conspiracy or no conspiracy. It is just too big a prize.

Nice. Now we've got examples of both Godwin's law and Poe's law in the same thread!
-
[crickets chirping] Sorry. I was trying to be at least a little bit subtle. [/crickets chirping]

I was making a joke with reference to Rick Santorum's recent comments, hence the [Poe's law] and [/Poe's law] tags.

Do dark matter/energy really exist?
PakledHostage replied to Rdivine's topic in Science & Spaceflight
I understand that Einstein rings, and in particular double Einstein rings like the one in the image below, are evidence for the existence of dark matter surrounding distant galaxies. Maybe someone with more of a physics background can explain further? -
Pffft... You clearly didn't read the previous 34 pages of this thread. If you had, you would know that it has been pointed out ad infinitum that several other countries quit the imperial system cold turkey. To my knowledge, none of them subsequently fell off the wagon.

Not to mention they're neat to look at!

I found these public relations relics on YouTube (one from Australia and one from Canada):

Chance of seeing auroras tonight
PakledHostage replied to PakledHostage's topic in Science & Spaceflight
For anyone who might be located in a favorable location, (i.e. far enough north to see auroras but far enough south that it actually gets dark this time of year), NOAA's space weather prediction center is forecasting that the current major geomagnetic storm (G4) will continue over the next few hours. People in the northern UK and southern Scandinavia might get a show tonight if they're lucky. EDIT As of this writing (~0230/23Jun2015 UTC), activity is back up to G4 "severe storm" levels. According to the Space Weather Prediction Center, G4 means the following effects can be expected: EDIT 2 I went out to see if I could photograph something, but the city lights were too bright. I could make out a greenish tinge on the horizon, but nothing worth writing home about. Those of you on the Canadian prairies right now and away from city lights might have better luck: -
Or we could sit back and enjoy the portrayal of a good story for once, and try not to dwell on the allowances that they had to make for the story to work as a movie?

I have to say that I support the online campaign to name one of the barges after another of the ships in Ian Banks' Culture Series "only slightly bent". The campaign was to rename "just read the instructions" as "only slightly bent", but given their record so far, the name will be fitting for the new barges soon enough, as well.

Gray, moist and squishy?

Are there trains nearby? Maybe it is a reference to Trainspotting?

I'm not sure I get your point? We all learned how to calculate the volume of a cylinder in about grade 7 or 8? If you work your example, you get an answer in cubic millimetres. There are 1 billion cubic millimetres in a cubic metre and 1000 litres in a cubic metre. If you divide the magnitude of your answer in cubic millimetres by 1 million (1x10^9/1x10^3), you'll get the volume in litres.

Yes. I was agreeing with you. Sorry I wasn't more clear. I was just expanding on what you wrote for anyone who might be interested. As you know, one can calculate latitude without knowing the time but an accurate timepiece (chronometer) is vital to all practical methods of determining longitude at sea. This is why the work of John Harrison in developing clocks that would keep accurate time while aboard a moving boat was so important to the British Empire. Prior to Harrison's invention of the chronometer, time was calculated by measuring the distance between the moon and other fixed objects in the sky. This took a lot of math and wasn't easy to do while at sea. Another method was to reference transits of Jupiter's moons using a telescope but, again, it wasn't practical to do this while at sea.
