Yep, Heliocentric is a great, and probably simplist model, but really, it's all relative frames of reference, and you can choose any frame of reference you want. As one person here says "In fact, the world does revolve around me, I get to choose the frame of reference"
Is it the best/simplist model? Nope. Is it a VALID model? Prove to me it isn't
It's all relative - Heck, Einstein talked all about frames of reference, and they apply to orbital mechanics too
Best off buying a mount UNLESS you happen to have access to a serious machine shop, THEN you can build some VERY nice mounts, but you probably would NOT be asking/., but looking on the ATM (Amateur Telescope Makers) list and sites dedicated to ATM(some HINTS there for anyone looking to build)
Remember some interesting things - with a SLOW turning device (and a drive IS), there is a debate RE Ball/roller bearings, and some sort of solid bearing (Bronze, PTFE, Molgice) - One will introduce periodic errors as the ball turns (depending on quality of bearings), the other can have 'sticktion' issues
Of course, another big issue is drive gears. The better quality the gears (paricularly the worm) the less periodic errors, and the better the scroll the worm attaches to, the more accurate the drive
Been a while since I've messed with this, but I often wonder of THE way to eliminate this is a friction drive of some sort - do away with the worm/scroll gears, and go to a pair of rollers, sor of like what "puck drive" turntables used to use
Look at the size figures for a Volt - It's a tad SMALLER than a Honda Civic - OK, I buy a Civic Sedan at $15.6K, save myself $8k, never mind the $2K or so it will cost me to run 220V power out to my detached Garage (I looked into it for other reasons) - and at the price of Electricity in NYC - $0.268 after all taxes, delivery charges, SBC/PRS charges, Temporary NY State Surcharges etc, so I pay more per kWh than I would for gas
The Civic supposidly gets 25/36mpg, while the Prius supposidley gets 48/51 - so Let's say the Prius gets 2x the Mileage of the Civic, and use that as a basic stand in for the volt right now - or say the Prius gets the same "basic" electric mileage
Using your $2.75/gal =.23/kWh, and figure the 6K miles/year we dive on our 'commute' car (aka the one we use for short trips), the Civic would use 320 Gals, or 1464kWh, for a gas cost of $880/year, while the electric would use 732kWh, at a cost of $196.18/year, leading to a savings of $638 per year to drive the electric - BUT, that inital $10K cost takes 14.6 YEARS to pay back, assuming NO interest on that 10K - Let's call it 15 years for break even
actually, in MOST states, the law is either moot on allowing your daughter to have a beer, and in many states (I think it's 19) there are specific exemptions allowing a parent to give alcohol to their child (I know NY is one of them)
"Contrary to popular belief, since the National Minimum Drinking Age Act of 1984, few states specifically prohibit minors' and young adults' consumption of alcohol in private settings. As of January 1, 2007, 14 states and the District of Columbia ban underage consumption outright, 19 states do not specifically ban underage consumption, and an additional 17 states have family member and/or location exceptions to their underage consumption laws."
Yeah, lot of drivers like that. The point I was trying to make is that there are a LOT of those signs that don't seem to mean all that much - like the ones you can do 50 in a moving van, and are signed at 30, and then every once in a while, in the same area, you get one that's NOT kidding. That one I sent pictures of, you're PUSHING it at the marked speeds (if you go forward from the second picture you'ss see LOTS of rub marks on the wall). The interesting part is that the trun coming INTO the cross Island on the other end of the parkway (Up by the Whitestone bridge for people who know the other area) is another bad one, but can be taken at higher speeds, if nothing goes wrong. Thing is, there have been at least 2 motorcycle riders killed on that turn recently who misjudged it, ended up in the weeds and dead. All thanks to the crappy designs of the "Master Builder" Robert Moses. That guy had a vision, BUT there were a LOT of mistakes in his designs, like highway ramps with NO acceleration/deceleration lanes
Always love the curve going from the Cross Island Parkway to the Southern Parkway on Long Island - Advisory speen is something like 30mph, and they mean it. What's fun is to look at all the marks/scars on the outside retaining wall of those folks who don't believe that they mean it
And if one of MY loved ones died because someone didn't run a lab because the MD didn't write "please", I'd be hearing them beg me to PLEASE stop by the time I got done with them - Heck, I'd be hearing them begging me to please kill them by the time I got done, to stop the pain
I hope the people who did this are enjoying using their phones. I'm sure all he has to do is say "here are the EINs of my real phones, turn off the rest please"
Yes - there WAS a reason for blood tests before getting married and the traditional 'no sex before marrage' deal back in the days before antibiotics and the pill. We may just end up back there. May be dull having only one partner all your life, but a lot of us have done it anyway
NYC has a LOT of very high end resturants, and I'll bet you that almost every chef uses some table salt in at least some salt (in moderation - I'm NOT talking fast food quantities here)
How much you want to bet that a LOT of the better chefs will move to Long Island, NJ or Westchester, and there goes the money from the high end dinning
" If you are an independent contractor, you own the copyright in the absence of a written agreement to transfer the copyright. Period "
Yes and NO - if you are hired on as a "contract employee" (aka a 3 month term kinda job) you fall under either part1, or if working as a team, the collective work part of part 2
If you are hired to produce a piece of work "I need you to write a program that does X" - then you DO own copyright, but anyone who does that without a contract, and where it does not explicitly transfer ownership upon payment is a fool
I've been there, for both conditions, on BOTH sides of the deal (Buyer and seller), and you have to watch this. I've BEEN in a situation where we were not getting paid, and had to threaten a copyright issue - We got paid..
That was my first idea too "Find an old MFM/RLL drive, and have at it" - then I realized, "You know, I'll bet that more than 1/2 of the readers of/. don't even remember them"
Actually, Aircraft , and for that matter, almost all machine shop work is done in decimal inches (of course except for fastener sizes, which are their own odd 'wire gage' sizes, but are not really added/subtracted), and measurements are usually NOT reduced to feet and inches, so you'll see things like 78.50 inches (and yes, the significant figures matter for tolerances, so 78 1/2 - which yes is sometimes used in old drawings is different than 78.5, 78.50 and 78.500)
So, yes, metric IS easier, but the inch system is not as bad as you think in doing industrial work )and yes, I have scales (what most of you would cale a ruler) that have 1/32nds, 64ths, 10ths and 100ths all on the same scale
You're so right that most "Valentine's Day" chocolate is frankly, junk. I get a box for the kids to eat.
Now, I know my wife LOVES Dark Chocolate, hates nuts, etc. There is a small bakery near here that also makes their own choclates - go in, pick the size box you want (Heart or regular, and have them put in it the assortment that YOU want. Yes, that little box of 6 or so pieces will cost MORE than a multo pound box, but it's what my wife LIKES
That, and I'll watch the kids, do the laundry and cooking, and let her have some time to herself - Hummmm
Back in the mid 1980s, I lived fairly close to Shoreham Long Island - Iwas one of the folks saying "Please start the reactor". I knew enough people who had checked and tested the safety systems (and watched a few of the test myself while I was testing MY stuff at the testing lab) that I knew it was the most tested reactor plant in history (due to all the controversy)
Sigh. I blame this all on Jane Fonda (et al) wanting to make money for their stupid movie
BTW - TMI? About as bad as it can get with a US designed reactor. They did just about everything wrong, managed to melt the core to rubble, and for all intents, nothing got out of the containment structure
I have a few trit vials around (smaller than the beta light) - in fact, each of my cats has one on their collar, so I can see them at night.
I can't remember what exactly the "hazardous" dosage is, but it involved a closed room, and something like 10000 vials
I was at some radioactivity experiment the other year, and they had a beta emitter - the point of the experiment was that a single sheet of normal paper is enough to stop beta radiation.

How about fixing the bluetooth stack so that we can dial from out handsfree device - and making a working voice dialer
No - award $1 - and NO legal fees - legal fees are part of the award - Here is your $1
Please? I'd award $1 - so that they can't appeal - they won, they got an award - now go away
