    The Graduate

    Well done! Congratulations to Will, and to his parents for being supportive of his ambitions and achievements. While the photo shows BJ in a suit, I think there is some probability he is either in bare feet or beach sandals.

    Sailing around the world in a San Juan 24

    Thanks for all your feedback on my simple math problem. We really need an update from Rimas to get this thread back on track (not that it really matters whether this thread is on any track at all). Go the Rimas!

    Sailing around the world in a San Juan 24

    Kinetic energy = potential energy (1/2) m V^2 = m g h (1/2) V^2 = g h V^2 = 2 gh V= SQRT ( 2 g h) g = 10 m/s^2 h = 1.5 m ( guess) V = SQRT ( 2 * 10 * 1.5) V = 5.5 m/s = 20 km/h = 12 mph Assuming the mass of the truck = the mass of the boat (a guess), Conservation of momentum: m1 V1 = m2 V2 Since the mass is the same, V1 = V2. The truck hit the boat at 20 km/h (12 mph) QED
  4. Plastic is made from hydrocarbons. Hydrocarbons are a source of energy. If there was a way to extract energy (safely and cleanly) from plastic, it would go from being a pollutant to a resource to be collected, bought, sold and used. We need plastic-burning electrical generating stations paying money for waste plastic. That would clean up a lot of the problem really fast. Anyone else have an idea on how to make plastic garbage a commodity?

    That's a cool undergraduate (or maybe high school) physics question. Knowing the mass of the boat and the height of the cab above the trailer, calculate the kinetic energy imparted from the black truck to the boat such that it had enough energy to be raised to that height. This is a simple application of the law of conservation of energy: conversion of kinetic energy to potential energy. From that, and knowing the mass of the black truck, work out the speed of impact of the black truck, assuming all if its kinetic energy is transferred to the boat.

    How do you define bad crew?

    I sailed on the big grey boats. Somehow those boats manage to (generally) get where they are supposed to be while loaded with all kinds of dangerous stuff (like bombs and aviation fuel), shoot at things, get shot at, and then (generally) return home safely. All this with a crew that includes borderline psychotics, sociopaths, drunks, drug addicts, criminals, ex-cons and people with very low intelligence (some barely literate / numerate). I think there was an expression that there are no bad crew members only bad leaders. Not really sure how true that was. But we worked with what we had and made the best of it.
  7. A substantial amount of air pollution in Canada is from the USA. The USA has also a significant polluter of the Great Lakes compared to Canada. The USA operates a lot of wholly-owned subsidiaries as Canadian companies. Revenue from those businesses flows back to the USA. Canada is an ally of the USA because, in the words of Noam Chomsky, it offers a long-term, stable supply of low-cost raw materials.

    SUV anarchy

    I have a 2007 Rav4. It has been a reliable grocery-getter (nothing but essential maintenance for 11 years) but is boring as all get out. As the guys on Top Gear might say, it has the handling characteristics of a shopping cart and corners like the moon. There is also a well known problem with oil consumption for Rav4s for this era (something about a piston seal but I forget the details right now). Mine burns about a quart between oil changes. The repair cost is more than replacement value and the recall repair is dependent on showing VERY high oil consumption (something like a quart in 600 miles). My next ride likely won't be a Rav4. But given the current car is just over 100k miles (I don't drive much) a replacement is likely at least 5 years away.

    “Knot” a cool pun: worst boat names ever

    There is almost an infinite number of good boat names. There is a small number of great boat names. A great boat name reflects something of the character of the boat, its pedigree and its owner. It is also highly personal and subjective.

    “Knot” a cool pun: worst boat names ever

    I saw a boat named "sail avee". Someone had to explain to me it is pronounced "say la vee" which in French is "c'est la vie" which translates as <with a shrug> "that's life".

    Do you live in a shithole city?

    And yet the United States War Department spends about $2B per day, every day.

    Republicans creeping me out

    Although it has been a while since I was in a Navy uniform, my recollection is that if someone saluted me and I am not able to return that salute (suppose I had both hands full carrying a large box), the protocol is to stand at attention and nod. That acknowledges the salute. If a foreign general saluted Trump, he could have stood at attention (surely someone could teach him how to do that) and nod. He could then extend his hand for a handshake. Nodding is not bowing. It is showing the salute is received and acknowledged. I'm not really clear on the protocol for the president saluting. Since he is a civilian, his saluting has always struck me as a bit odd. And usually presidential salutes are far from what is described as a salute in the drill manual.

    Retirement Anarchy

    I figure I am 3 - 5 years from retirement. As soon as my nest egg hits the point where I am confident I can retire comfortably (never worked anywhere that had a pension plan), I'm done.

    Todays Useless Fact

    Sorry, Sloop, but I gotta check your math (I'm an engineer - can't help it). An order of magnitude is a power of 10. To go from Mega (10^6) to Peta (10^15) is NINE orders of magnitude in 40 years, or about a factor of 10 (order of magnitude) every 4-ish years. Yikes. I started first year engineering school writing FORTRAN code on punch cards. It was hellish.

    Yes. I stand corrected.
