Internet Explorer? I mostly use Chrome, but when I access my company's internal website I have to use Internet Explorer. I think version 10 was the most recent for Windows 7.
The active system may seem overly complicated, but trust me, passive damping was looked at. There were 6 different isolation systems on the table prior to this final down-select. And in fact, the dampers at the mid-stage are entirely passive. They are enhancements to CSA Engineering's Softride system.
The active tuned mass actuators are necessary in the first stage because nothing else would work for the heavy resonant burn effect.
Resonant burn is something seen in all solid-fuel rockets where an axial oscillation occurs as the fuel gets used.
I took Air Force flight training back in the '70s. An altitude simulator was part of the training. The were at least 12 people with me. The need to pass gas as we ascended was interesting. When I took my oxygen mask off at equivalent air pressure to 24,000 ft, the atmosphere was a little heavier than I expected at that altitude.
The city where I live (San Jose) actually has a law against this. You can only pave up to one quarter of your yard. I suppose green dirt would be OK.

Oracle Linux?
·
· Score: 1
We used to run MSC/Linux as OS for running MSC/Nastran. MSC/Natran is the Oracle of finite element programs. We thought using MSC/Linux, which was based on RedHat, would be closely coupled to the application and make support easier. This was correct for running on the HP boxes supplied by MSC. When we eventually decided to upgrade the systems to dual-opteron, gigabit ethernet, raid, etc. we encountered many hardware/software incompatibilities under MSC/Linux. RedHat ran flawlessly on the new boxes. We told MSC we were changing to RedHat. They said we were making a mistake because we would not have the fine tuning they had done to the SMP kernel. We just had to buy hardware from their "approved" list. Of course their approved hardware was much more expensive than the third-tier boxes we had already bought.
Naturally, being open-source, we compared MSC's linux kernel source to RedHat. RedHat actually had a "new" SMP patch from the Jet Propulsion Labs that MSC did not have. We could not find any other differences. We have updated our hardware several times since (each time for at least a doubling of measured performance for our Nastran runs.) No hardware, no driver issues with RedHat.
We have been running RedHat ever since with no complaints.
I work at a consulting firm specializing in structural dynamics. We have designed and built parts that are on the Hubble telescope, have isolated payloads in the Space Shuttle, and are in the Airborne Laser, to name a few. Most of our engineers have advanced degrees in mechanical and/or aerospace engineering. We have one engineer with a PhD in Theoretical Mathematics. It took him a while to come up to speed in engineering, but he is a definite asset to the company.
Getting a PhD in mathematics will give you the tools to branch into many well-paying technical jobs.
Good luck.

My wife, who is an engineer, said, "I would go piddle, although boys would have better directional control."
It is not programming, but Phun is a good 2-D physics simulator for kids.
Another that takes a bit more work is Google's Sketchup with the SketchyPhysics plugin.
Call them inertial dampeners!
Actually, they are inertial dampers.
Wet towels are used for dampening.

They are not even pipe clamps. They are hose clamps. YIKES!!!
Many social insects have the capability for war. Have you ever watched ant colonies fight? A description of observed carpenter ant battles is at

I guess we humans aren't so special after all.
Yea, its one of my pet peeves as well. Do you notice how prevalent its' gotten?
Must control myself... Keep away from the keyboard... Can't... Ah Hell.
It's, "Yeah, it's one of my pet peeves as well. Do you notice how prevalent it's gotten?"
I feel better now.

Uh, Yes. Exactly.
"...and where Zeframe Cochrane launched his first warp ship from."
No. It's where Zeframe Cochrane WILL launch his first warp ship from. Get your facts straight.
Let's see.
1. Set up my 4-year with his computer account.
2. Give him an icon to click on, no password needed.
3. Make him root...
No problem here!
So, people viewing my Webcam of the neighborhood will cause me to lose my DSL connection?
