Just want you to know Ira, the reason I go to RadioShack is because I know next to nothing about electronics but your employees do. They, with their knowledge have saved me many times all without making me look like an idiot. So a BIG thank you to your employees. I will also take the time to give a shout out to the Athol store as they too have bailed me out more than once. Very Happy you will not be closing. ...(full comment)
The Spanish program in the younger grades is invaluable to these early learners. Maestro does more than just teach colors and numbers in a foreign language, he is a kind, loving person whom the children look forward to seeing each week. My children used to come home and teach us the Spanish songs and games Maestro taught them. I will certainly be at town meeting to vote not to lose this wonderful and important part of our early learning curriculum. How sad that just because the older students don't have the benefit of Maestro's instruction, we should take this away from everyone....if we were smart we would vote to extend Maestro into the upper grades to give the children at DES the edge they need heading into Frontier. ...(full comment)
I would be interested in knowing what type of weapon the police are going to carry? Will they be assault or hand guns? Just hoping if the need ever arises that these officers are well equipped to handle the situation. ...(full comment)
So you are going to let people know when and where you are going to be in the future ^ ^ ? All is not well in the PD, maybe you should pay a little more attention to your officers 2 bit role in the BFMC soap opera. This is not the time and place right now but you will be hearing from me. For those of you that really give a damn... TY
The angular momentum of an oblique impact of a Mars-sized 'Theia' necessary to form the Moon appears to obviate the leading hypothesis for the formation of 'Theia' in one of Earth's stable, L4 or L5, Lagrangian points.
Calculation of the pre-impact 'offset velocity' of a Mars-sized planet, 'Theia', which grazes Earth's limb (Earth's 6,378 km radius) with a pre-impact 'linear offset momentum' equivalent to the post-impact lunar angular momentum.
Mass of Moon: mMoon = .0123 mEarth
Mass of Mars: mMars = .107 mEarth
Semi-major axis: rMoon = 384,399 km
Average orbital velocity of Moon: vMoon = 1.022 km/s
Radius: rEarth = 6378 km
L1 = L2
(mMars)(rMars)(vMars) = (mMoon)(vMoon)(rMoon)
(.107 mEarth)(6,378 km)(vMars) = (.0123 mEarth)(384,399 km)(1.022 km/s)
vMars = 7.08 km/s
Since low Earth orbit begins at 6.9 km/s (ignoring the barycenter offset of a Mars-sized body as a rounding correction) a (point-sized) Mars-sized body, 'Theia, in low Earth orbit has the same angular momentum as the Moon! This pretty much shoots down one leading contender for Theia as a co-orbiting planet formed in one of the two stable Lagrangian points, L4 or L5, since anything formed in Earth's orbit would have next to zero angular momentum relative to Earth
Another way to look at it, is that for a Mars-sized body falling toward Earth to just graze Earth's limb with its center of gravity would require an initial tangential velocity relative to Earth of 7.08 km/s (added vectorially to the radially directed 11.2 km/s escape velocity) which couldn't be attained in Earth orbit starting from a stable L4 or L5 Lagrangian point. ...(full comment)
Really? Social equality? What does that mean exactly? How does that get put into a city's Master Plan? That's a first. How about "compatible land use" or "compatible economic growth". When speaking of "districts" in the master planning process, do you have a district where all people are socially equal? I hope they didn't spend too much money on this thing. ...(full comment)
Perhaps when you're a little older, you'll realize that it gets cold every winter; and that this fact neither confirms not refutes global climate change (no doubt your teacher can explain that it's summer elsewhere on Earth).
As an exercise, I suggest you make a list of the cold temperature records that were broken this and recent winters and compare them to the warm temperature records broken recently. ...(full comment)
Heroin is coming on the streets more pure than in 5 decades - we are losing the "war on drugs" because too much focus is put on pot and pain killers. As an addict (35 years clean) I KNOW what I'm talking about. I cringe when I hear remarks that those drugs lead to harder drugs - it's a lie perpetrated by politicians & law enforcement to con the public into believing they are accomplishing something - every dollar & every resource needs to pour into getting dealers of heroin, crack & coke off the streets - those 3 drugs are as easy to buy as a six pack - dealers in small suburban areas slide in from metro hot spots - hole up in hotels, poison children with too much access to money and EVERYONE knows it ... except the cops. ...(full comment)
