Who here /cityplanner/?

What alternatives are there for roads and highways. One of the biggest problems overlooked in today's world is congestion of cities and time wasted in traffic. Not to mention, pollution, noise pollution and a big contributor of stress.

Thinking ahead, populations will increase and congestion from suburbs to the city and vice versa will inevitably get larger and larger. Are there alternatives to roads and transportation of people and what can we do to fix this?

Stop letting people park on the fucking side of the roads
Auto driving cars so you don't need parking lots everywhere.

Elevated tracks for light rail

Or just legalizing light flying vehicles over urban areas.

in what way was the eugenics movement in the 1920-1930s wrong? It seems like the modern welfare state and modern medicine simply encourages those less intelligent and with genetic flaws to breed more.

Why shouldn't we try to improve the general genetic health and intelligence of the human race by say sterilizing the bottom 1-2% every year?

>in what way was the eugenics movement in the 1920-1930s wrong

>much of the original movement was not aimed at African-Americans. According to Leon, the system of racial segregation in the U.S. was such that most eugenics advocates did not perceive a "threat." Rather, it was aimed largely at the immigrants from southern and eastern Europe who came to the U.S. in great numbers between about 1880 and 1924. These were largely Italians, Poles and Slavic peoples.

If a physically immature(Growth plates not fused yet) teenager was injected with HGH, would they begin to increase in height, or would their body react negatively?

please don't do this. this is so stupid and foolish.

yes they would grow taller

it's an absolute shame shorter guys can't get this done.

you just have to be careful with the dosing because you can stunt your growth if you over do it

I wonder if Donald Trump has somehow arranged for his son Barron to receive such injections. He's 10 years old and 5'9" or so.

How does one get into a career in neuroprosthetics? I mean, this field must involve teams of surgeons and neuroscientists, right?

Which undergrad program should I go into? And where do I go after that?

it just not fair that you can just die from one moment to another from brain bleeding. it doesnt matter who you are or how young, healthy you're.


its not fair

It's a crushing realization. Not as soul crushing as actually experiencing a stroke out of the blue and becoming and half-retarded, which IMHO is much worse than just dying. Aneyrisms are bad, but brain damage is horrible.

Also yeah, this too me a while to realize too, but the brain is just tissue. It's part of the body. It will bruise and bleed and die like anything else. It degrades with stress factors and age.
It's a fact. Death is inevitable. Sorry.
>>
Well, you can also die at any moment from a falling meteorite, or being swallowed by a sinkhole, or being crushed by a falling suicide, car crash, choking on an almond, street violence, electrocution, and 1001 ways to die.

You should never take life for granted, talking about enjoying every moment as if it was the last sounds corny and cliché but it's true.

Maybe you died in the time lapse between your post and my reply.

Hey, everyone, I'm hosting a survey on how people view heroin abuse in America. Any and all feedback is welcome.

Former junkie here
I believe you can put whatever you want in to your body and there shouldn't be legal consequences, since I've known junkies who shot up everyday for years and survived yet I can go to mcdonalds and stuff my face for breakfast, lunch, and dinner every day for a month and die from a heart attack.
As someone who no longer shoots up, I think drug addicts are losers, because I know I was a loser when I shot up. Rehab/NA/AA are all useless, all I had to do was move away and when I didn't have a hook up I didn't do heroin. I don't see why living your life about not doing drugs is going to help you stop, its all about discipline, really.

I want to believe, but it could something as simple as an electric arc from the powerlines or some kind of anti-missile system or something.

possibly but would it really light up the sky that much?

In New Zealand? don't think so

Hello, I am breddy gud at math but equations with log, ln, or e trigger the fuck out of me. I don't know why but I just can't seem to solve them. What are some good ways to simplify log-based equations?

You can represent logs as exponentials with unknown powers, that's all logs are for, but really what you need to do is just do more problems until you're comfortable with the functions themselves. If you're going higher than precalculus in math, I guarantee you will see log and ln in all of those math courses besides maybe statistics and intro to linear algebra. Do more problems.

Can a person lose their intelligence in the span of 3 months? can you turn from brilliant in maths to downright stupid? what the fuck?

It's totally possible, for example by interacting with females. Females are draining your resources without giving back anything in return.

Of course, it doesn't even take three months, it can be done in the fraction of a second, just hit your head hard. Or have a stroke or something.

it has come to my attention that our current theory of gravity is flawed at its very core, requiring special relativity to even pretend to explain it. the biggest and most fundamental floor in Einsteins theory is that his supposed fabric of space can curve and stretch. Now we all know a universal fundamental law stating that any action must have an equal and opposite reaction this means to return to a resting state space must at some point collapse in on itself according to Einsteins theory as space obviously holds some elastic property to him. singularities should exist where ever there is movement of mass.

i have been pondering if you will for the last few years a theory that could rectify this error. in my endeavors i have come across bits and pieces of Teslas theory of dynamic gravity, i hadn't thought too look it up it till recently at which point i found it is classified, which struck me as very odd, why classify useless information. ive done some digging since and cant find much. a few people ideas and what not but noting solid.
id like to know what yous yous think, maybe someone could help me figure out the math involved it and to piece together the missing bits

heres a rundown on what can be pieced together of his theory that the public have access to
All ponderable bodies are constantly in motion in through space.

Absence of a medium would result in no electromagnetic forces (the space-vacuum fabric is a medium, the aether (the ultimate medium))

Ponderable bodies and other media filling space all possess a dielectric level.

Motion through space produces the "illusion of time".

Mechanical effects are produced by electromagnetic forces acting through media (i.e., momentum and inertia is electromagnetic in nature Energy is force over time)

A media exposed to resonant vibrations of electromagnetic force interact.

Electromagnetic energy fills all space (referred to as radiant energy).

Electromagnetic force is a phenomenon produced through the medium in space (eg., the result of the medium acting upon ponderable matter).

Modulating Wideband frequencies of electromagnetic phenomenon permeate through all media (akin to spread spectrums).

Self-regenerative hetrodyning electromagnetic fields condense through the medium in space.

Electromagnetic potentials arrange themselves in groups according to the medium's polarization and the medium's dielectric resistance.

Electromagnetic fields interact and produce rotating fields.

Electromagnetic entropy returns energy to potentials.

Electromagnetic potentials of high frequency produce: [a] lower environmental interaction, [b] uniform movement without rotation through space-time, and [c] electromagnetic saturation [i.e., plasmas]

Stationary low frequency electromagnetics behave as waves.

Medium's electromagnetic fields creates attractive forces from negative polarity [or what is commonly referred to as "gravity"].

Hoo boy, OK, let's do this.

>to return to a resting state space must at some point collapse in on itself according to Einsteins theory as space obviously holds some elastic property to him

Those are all words spelled correctly and they definitely form a sentence. Great job! Now some questions for you.

What is the "resting state" of space and why must space return there?
Why does elasticity imply a point of collapse?
Are you saying that mass exerts a force on space, and that space should apply a reactionary force back?

>the public have access to

Link? Source?

Now what follows in your post is a whole lot of stuff that maybe means something to someone. Maybe you are suggesting that electromagnetism and gravity are really the same force? Because no, that's definitely not true.


But let's just for a moment forget the answer you're looking for and confront some more practical questions.

Let's suppose that Einstein is Wrong and They classified the Right Answers.

How many of Them are there?
How many people in government, in physics, in industry, know the Right Answer? How many make sure that people like you and me learn the Wrong Answer?
How much money would any of these people stand to make by leaking the Right Answer?


You're one guy supposedly pouring over sooper seekrit Tesla notes and you're the one who's cracked it? Find a better and more realistic goal to set yourself, because while you might imagine the day that everyone sucks your dick for saving physics as we know it, I hate to break it to you but it's just not going to happen.

The egomania necessary to convince people that one's lack of understanding of a theory is actually a flaw of the theory never ceases to baffle me.

These two are twins from the rock band Biffy Clyro. One thing always have took my attention is how the drummer has being losing hair til going completly bald while his twin has a good and healthy hair.

Thoughts on it?

Are they identical twins?
Otherwise environmental factors could be the cause

>>8469212
I have a twin brother who is also going bald while my hair is fine. The key is we are not identical twins.

Definitely. Get lots of sun on that head and don't wear head wear all the time kids.

>What is the future of nuclear energy technology

1. Higher Efficiency turbines. Super-critical or Brayton cycle turbines can bring efficiency to +40%. Save money, increase profits.

2. More Compact designs and Digital Controls. Save money and improve safety.

3. Standardization on fewer models. Easier maintenance and supplier predictability, lower costs.

4. Lower Enriched Uranium or Thorium fuels. Lower processing/mining costs.

5. Thermal/Fast spectrum breeders. Will increase fissile material and extend the sustainability of existing fuel for a very long period of time.

>will it ever experience a 'boom' period of rapid growth

It is booming in Russia, Korea, China, and India right now. Western countries are no longer leaders in this technology. They will probably start adopting it after they realize there is no other realistic alternative, and learn from their Eastern counterparts. Unless Fusion can happen commercially, instead of being an eternal meme.

>>8468971
It experienced a boom in the 1960s and 1970s in the US, and in the 1970s and 1980s in France and Japan. It's currently experiencing a boom in China.

Cont.

That said, I think over regulation - despite the lowest fatality rate of any energy source - is the death of Western nuclear. Any thoughts of reducing regulation is political suicide. The best way would be to avoid it would be to move towards liquid fueled reactors that need less expensive safety systems.
