Gasoline vapors are heavier than air and can creep along the ground. That makes gasoline more dangerous than hydrogen. An outdoor tank of gasoline is more dangerous than an outdoor tank of hydrogen. Burying a tank of gasoline has the additional risk of contaminating groundwater and soil.

KGS, the Kiseido Go Server, is a wonderful way for new and experienced players to enjoy the game of Go. It has a great user interface including the best support for teaching and reviewing games. The programmer, Bill Shubert, is a genius.
At times there are over a thousand users and hundreds of games on the server. There are many rooms. One of the most popular is the Beginner's room (in the Lessons group of rooms). Ask for it. KGS runs tournaments every so often. Some championship games are broadcast live. Professional players give lessons for hire and many strong amateurs will play you a teaching game. There are sometimes free pro lessons.
There are many tips and much discussion about KGS on Sensei's Library.
It runs on Linux, Mac, and Windows. It is free of charge (no charge for users from Japan or anywhere else).
Build the parabolic blast shield in sections and float or drag them into place to minimize vibrations.
When it is in place, gently drop the world's biggest blanket(s) on it from remote controlled cranes or airships. The blanket can be fabricated from cheap light weight biodegradable material, probably recycled in some way, or agricultural fiber waste. When in place, hose down the blanket.

Light is not an electric field, it is a propagating electromagnetic wave particle duality.
To address your other point, electric fields can be very damaging when they are sufficiently high intensity. Also, electromagnetic fields can be damaging too.
Not damaging to the water molecules, which are robust, but damaging to the materials disolved or suspended in the water, which may be delicate bio-active organic molecules. For example, there are various cell sorting systems that currently use electric fields. They might better use a system like this.
However, light can be damaging in its own right. Red and infrared light can be heating. Violet and UV light can be energetic and penetrating (think sunburn radiation damage).

When film was very new (1900's, 1910's, even into 1920's), projectionists would travel from town to town and show films this way, outdoors.
There is a semi-regularly scheduled monthly movie showing like this in the San Francisco Bay area these days.
This is kind of like Closed Source for cars and other devices. It is nearly impossible to buy an appliance that can be fixed these days.
Do It Yourself is one of the key sources of training and background for scientists, engineers and technicians. Second sourcing is having more than one source for components and parts. This is very necessary for competition and vitality. No lock-in.
The alternative is for half the people to become narrow hyper-specialists and the other half to be totally out of it. That's ok for maintaining a status quo, but won't advance society much.
Your background reading, a classic: "Little Black Bag" by Cyril M Kornbluth, a future wherein a tiny fraction of humans are educated and the rest just coast along comfortably numb. A doctor's bag gets sent back to the 20th century.
Dan O'Dowd doesn't have a clue. He is ignorant (willfully or otherwise) of the Open Source truism that "many eyeballs make all bugs shallow" (Eric Raymond).
Contrast this with proprietary closed source. In that environment, it is easier for a terrorist mole to introduce a trojan horse that won't get much inspection on its way onto millions of systems.
Beta waves (about 15 Hz to 40 Hz) are associated with concentration and calculation. Alpha waves (about 8 to 11 Hz) are associated with calmness, creativity, and being "in the zone". Theta waves (about 5 to 7 Hz) are associated with hypnogogic states: drowsiness and the state of just waking up or falling asleep. Delta waves (about 1 to 3 Hz) are deep sleep waves.
To address your initial point, ADD and related disorders may be connected to a deficit of alpha brain waves. Although the increased beta activity leads to concentration in small bursts, a lack of calmness leads to great distractibility. ADD can be helped by techniques that enhance one's ability to generate alpha waves. Alpha waves are constantly being generated by the thalamus but can be swamped by other brain activity by time they arrive at the cortex.
All of these brainwaves can be trained for with neurofeedback training. I have received training at the Biocybernaut Institute and I can recommend it as quite remarkable on several levels.
Not surprisingly, caffeine stimulates beta activity and suppresses alpha and theta. Meditation increases alpha ability and advanced meditators get into increased theta while maintaining wakefulness.
Beware of entrainment systems that channel the brain into fixed frequencies with blinking lights or beat frequencies. Proper brainwave training is completely driven by the trainee's own brainwave patterns which are rewarded with positive feedback.

Originally, androids were hybrids that used genetic engineering for a mostly carbon-molecular platform. See "Do Androids Dream of Electric Sheep" by Philip K. Dick, which became "BladeRunner".
These days, you would have to add nano-tech to the mix. Considering that computers, gene-modding, and nano-tech are the three legs of the future tech tripod, the lines are going to get blurred very quickly.
The "andro-" root means male, though "android" may have been coined from "androgynous", meaning both male and female. Somebody with access to OED online please look up "android" and reply to this post!
In South Africa, a "robot" is a traffic light (red, yellow, green), not even necessarily with a sensor embedded in the pavement.
Son:Gee Dad, schools is for the birds! Father:Yeah, it sure can feel like that sometimes. What would you like to get out of school? Son:I wish there was practical stuff, like a shop class on cars. Father:Hmmm. How about we get a good sporty car that's beaten up and then you could fix it up? You could read up the manuals and I could help you with some of the concepts and when an extra pair of hands are needed. If we get stuck we could pay a mechanic to teach us a couple of tricks. If you do a really good job we could even enter it in a drag race or two at the fairgrounds. Son:Cool! Father:In the meantime, could you try to study hard in that stats chapter coming up and in your physics lab? We're going to be making measurments and needing to make decisions on things for the car. Son:Deal!
Is the whole "Math is Life" concept a bunch of fluff that serves itself or can it really be applied in a *real* sense often? Is math a highly important part of excelling in greater understanding?
Yes, it can be applied often and yes it helps greater understanding. The application might not mean actually calculating things, but mean understanding the mathematical organization and relationships.
The greatest way understanding math can help enlightenment is by enhancing imagination. With an expanded imagination we can analytically divide things and processes down to more manageable pieces. Alternatively, we can aggregate things to help us see "the big picture" or the bigger picture if not necessarily the biggest picture.
Many times we apply mathematics intuitively. When a wetware processor uses neural networks to calculate a complex bank shot in pool, it is not a mathematical calculation in Newtonian sense, but it is nonetheless a mathematical calulation based on sensory inputs that cause precise adjustments to actuators (muscles). In doing so, we break things down mathematically (but still intuitively) to such questions as how a bald spot on the felt might affect the ball. We also aggregate things mathematically in social calculations such as answering the question "If I make this shot, will it help or hinder my plan to hustle these guys for money."
Math has so many varied techniques and ways of looking at things that it is very enlightening. There are of course calculus, logic, graph theory, group theory, statistics, discrete structures, computability theory, and fuzzy versions of these, to name just a few obvious ones.
Math can be applied to business, engineering, programming, sociology, ecology and many fields. Seeing some of the ways in which math can be applied is enlightening too.
Beyond this, understanding math also leads us to an understanding of its limitations. One can trasmute the famous zen homily into this one:
Before math, mountains are mountains and rivers are rivers. When studying math, rivers are seen to be immensely complex mathematical phenomena. After studying math, mountains are once again mountains and rivers are once again rivers, but one can see the complexity anytime one chooses to.
Please do not discard applied math because pure math seems too idealistic. In the repeated binary division example you give, simply decide what is the smallest linear dimension that can practically be cut (in practice, i.e. in pragmatic application). Then use the math until the linear dimension falls below this threshold and you have determined how many cuts you can practically make.
One could say that even this is too pure, in that practically speaking, we tend not to make perfect cuts and apples tend not to be perfect spheres. We can then apply statistical techniques based on measurement of actual sample apples and actual performance tests of cutting. Working it through, we would arrive at a result that would be phrased similarly to this: about 95 per cent of the time we could make X number of ordinary cuts to ordinary apples before we would have a 50 percent chance of failing to be able to cut.
Applied math does not fail in the extremes. One way it helps is to determine what is a practical extreme.
There are many ways in which math can be used to help define what is "good enough" and then optimize how to get to "good enough".
