It might as well be a picture

residentsim:  Good way to change the subject. 

[astronelson 339]

1023. Aw, science is great! Why'd you have to go and change the subject on us?

[Keegan V50 15]

1024....nice train there RS

[Korot 6]

1026. Justice, you forgot to post a number, and Astro didn't correct it, which he usually does.

[Vahr 343]

1027. Blah, sometimes people don't bother

Oh, and random news about me: I actually aim to keep this avatar for at least a week. I like this one

[GlobexCo 33]

1028 @blue Lightning: My favourite avatars are animated gifs... you had some good gifs!

[Larks2242 251]

1029. Wow almost a page without my help

[Korot 6]

1030. Yeah, almost.. Indicates how fast it goes.

[Vahr 343]

1031

Well we are trying to get to 10,000... and larks you just had to pop in. We almost made it

GlobexCo: you mean this one?

 1032 Yes, very funny...

[Muck308 55]

1033 I get the urge to change my avatar often, but usually resist the temptation. But I think I'll be due for a change in the coming weeks.

[citiesxlfan42 27]

1034. What I've done today...

Destroyed a demonicly possesed globe

Ate soup

Got on the honor roll

PLayed some of the best Basketball of my life

Listened to a lecture on Geologic TIme.

GO HADEAN EON!!!

[Larks2242 251]

1035. Hmm...looks like my post never went though due to the server crashing. btw that's a odd sonic avatar Blue.

[Vahr 343]

1036

Larks: The current one? Yeah it kinda deviates from my usual. Its from an artist that specializes in semi-anthroMobian (sAnM) Sonic art in the Fleetway universe (sAnM_%FW). This happens to be his rendition of an "older" Sonic. Of course most of you have no idea what that means, or just don't care.

EDIT: Seems like I'm post ID 1,650,050 Interesting number.

 

[astronelson 339]

1037. I plan to change my avatar about twice a month, although this is subject to monthly variation/future whims.

[Larks2242 251]

@ Blue You lost me on the first setence i have no idea what you mean i do think it's cool never seen sonic as part human before

[DCMetro34 577]

@ Larks, I guess that's 1038. Mine is 1039.

[Keegan V50 15]

^^ Yep,and ill head in to 1040

[Larks2242 251]

and i'll make number 1,041

Duke, I think kph still technically falls under SI, since its simply a *1000/*360 conversion. Also you don't see highway signs saying "150 m/s" now do you?

Well, first of all, considering that 150 m/s is equal to 540 kph or about 335 mph, yeah, it'd be pretty outrageous to see that on a highway sign.

And no, kph is not SI because hours are not SI. Seconds are the SI unit of time. Based on that, a millisecond is a valid SI unit, as is a kilosecond, megasecond, etc. - but an hour is not, nor is a minute, day, week, year, etc. Any SI unit of speed would have to have seconds as the denominator. In base form, that means meters per second, although prefix multiples like millimeters per second or kilometers per second are also acceptable.

The biggest problem with using meters per second for highway signage is just it's generally not layman's terms - fixable, but a bother to fix.

Practically speaking, the unit is a bit on the large side, but it's still manageable....

5 m/s = 18 kph ≈ 11 mph

10 m/s = 36 kph ≈ 22 mph

15 m/s = 54 kph ≈ 34 mph

20 m/s = 72 kph ≈ 45 mph

25 m/s = 90 kph ≈ 56 mph

30 m/s =108 kph ≈ 67 mph

35 m/s = 126 kph ≈ 78 mph

All those quiet 20 and 25 mph side streets can be 10 m/s. The 30 mph city streets and occasional odd 35 mph zone can be 15 m/s. 45 mph thoughroughfares match up quite nicely with 20 m/s. 55 mph urban freeways, 25 m/s. 65 or 70 mph rural freeways, 30 m/s. And those 75-80 mph zones out west can be 35 m/s.

Of course, the US has to finish its gradual thousand-year plan of going metric first.

[astronelson 339]

1043. The highest speed limit near my house is 275/9 m/s. The standard road speed here (where unsigned, built-up areas) is 125/9 m/s, but most areas are signed to 50/3 m/s. Unsigned, rural areas are limited to 250/9 m/s.

This is, of course, nothing compared to the 299,792,458 m/s speed of light.

[Larks2242 251]

1044. Here we go with the math again

[Vahr 343]

1045. Duke I guess you're right

The speed of light is approx Mach 881,742.5 according to the data gathered here. (340 m/s SoS, and Astro's SoL)

[DCMetro34 577]

1046. Guys, we have about 9,000 posts to go. Am I going to have to deal with Math half the time? I only like Math from 8-9 A.M.

[Hamish 1,370]

1047. No, they will get over it soon enough...

[Larks2242 251]

1048. Hope so Hamish

Two problems with this assessment.

First of all, you're comparing the speed of light in a vacuum to the speed of sound in air, so it's not apples to apples. Secondly, the speed of sound varies somewhat based on temperature (and negligibly due to other factors). The 340 m/s figure is just a nice round number which is about correct for 15°C, but not for all circumstances.

[Vahr 343]

Thus the reason of the word "approx." And since sound has quite a hard time traveling through next-to-empty space, its the best you can get to. And I am aware that sound speed varies by temperature, pressure, density, and other factors. You don't always have to be precise 99% of the time ya know.

*random* Helicopter just flew over house at time of writing.

And I'm getting a tad tired of this math too. Can we talk about oscillating potatoes for once?
