For instance, does it have to do with balance? Equilibrium? Why do we not have an intrinsic ability to ride a bicycle?
Answer
See the great web site below:
http://hyperphysics.phy-astr.gsu.edu/hbase/mechanics/bicycle.html
When the bicycle wheels are rotating, they are stable. The magnitude of the stability depends on the velocity of wheel, the radius of wheel, and the mass of the outer part of the wheel, the tires and rim.
A young child on bicycle with small wheels traveling at low velocity is very unstable. When my sonâs were learning to ride a bicycle, I would give them a push to increase the velocity of the wheels. As they became more comfortable, less afraid, they would run and hop onto the bicycle after the velocity was increased.
I am now a 62 year old man who has Normal Pressure Hydrocephalus. This causes me to have balance problems. Last summer, I felt like the child just learning to ride. I would start at the highest point of our driveway. The velocity of the bicycle and me increased as we rolled down the incline. Thus our stability was increasing, and I felt more comfortable, less afraid.
That was the easy part.
When I got back home, and rode the bike up the incline, the velocity of the bike and me decreased. Thus our stability decreased.
As I almost came to a stop, my stability was decreasing faster than I could climb off the bike. Yes, the bike and I fell to the ground. Now, I make sure that I am next to my car, when my velocity is low, so I can lean on the car and safely get off the bike.
I last physics connection!!
Before I had these balance problems, I would ride with no hands on the handle bars.
As I leaned to the right, the front wheel would turn to the right and the bike and I would ride around a circular arc at a junction of 2 streets.
As the plane of the rotating wheel is shifted away from vertical, a torque perpendicular to the plane of the circle in which the wheel is rotating. To counter balance this torque, the front wheel rotates, causing the plane of the circle to rotate. The result is the front wheel is causing the bike and I to move in a circular path.
What scientific principles are involved in learning how to ride a bike?

To counter balance this torque, the front wheel rotates, causing the plane of the circle to rotate. The result is the front wheel is causing the bike and I to move in a circular path.
When I lean, I apply a force that attempts to make the wheel lean at the same angle. If the bike and I were sitting still, and I leaned a specific angle, the bike would lean the same angle. However, rotation of the wheel increases the moment of inertia of the wheel. As I lean a specific angle, I am my body is exerting a force that is doing work that produces a torque that is causing the plane of the moment of inertia to change its direction.
Energy always tries to be conserved. So, the energy produced the work, that caused the front wheel to rotate, which cause the bike and I to move in a circular path.
The force is now centritptal force

What is the difference between a feminist critique of pornography and a conservative/traditional critique?
Taylor
I am working on a essay and am having a slight difficulty with part of the prompt. Any help at all would be amazing.
Answer
Feminism sees the world as a competition between Men & Woman for power... rather than the Darwinistic premise that it's the cooperation between Men & Women to create offspring.
Which makes Feminism stunningly incapable of providing a logical foundation for any sort of real world analysis.
Is sexual attraction part of a Woman's Power?
Or is it a Masculine trap to enslave Women to the drudgeries of raising children?
Well a Feminist doesn't know, it all depends on her mood that morning. Whether she's a bull dyke or a fem fem. Whether she's attractive or resents that the 'hot chicks' are catered to.
However in general Feminism has been dominated by somewhat unattractive lesbians. I.e. the "A woman needs a man like a fish needs a bicycle" types.
Which means they construe Pornography as Men exploiting & objectifying Women. I.e. Porn is bad because it encourages men to see women as 'sex objects' rather than people worthy of respect & equal pay.
The notion that Men are exploited by pornography, i.e. trading their hard earned dollars just for an inconsequential viewing of nudity - doesn't really enter into Feminist thinking... Men are the enemy, if their desires cost them, that's just karmic justice.
Conservatism is defined by 2 fundamental principles.
1) Do what you have agreed to do.
2) Respect the property of others.
Which means "Conservatism' has no critique of porn per se, other than paying the models what you've agreed to & you shouldn't steal your buddies Playboys.
What does have an opinion on Porn is Christianity.
Now Christians are usually Conservatives because the Conservative fundamentals correspond with the last 5 Commandments.
BUT Christianity is far more Darwinistic than simple Conservativism, keeping in mind though that Christian tenants are presented as 'The Word of God' rather than the Darwinistic principals for successful procreation.
None the less, even a cursory evaluation of Christian principals reveals it's all about creating families to raise babies.
And if anything isn't good business ethics or family values, it's probably a sin.
Do Gays make babies? Nope, so being Gay is a sin.
Does Abortion kill babies? Yep, so Abortion is a sin.
Does Promiscuity make babies? Well, maybe, but it doesn't help make families so Promiscuity is a sin... unless you marry the girl you knocked up... which Christians call 'doing the right thing' & then you are forgiven.
So what is the Christian critique on Porn? Well it's a sin.
It's lust instead of love. It's money wasted on sexual desire that does not promote family formation.
Christianity rejects the divorce of sexual desire from responsibility to offspring. It rejects the Playboy philosophy. Sex is fun, but it's not for fun. Women are to be Mother Objects, not Sex Objects.
And in that bare sense of objecting to pure sexual objectification of women, the Christians agree with the Feminists....
BUT... the agreement is profoundly short lived, because Christians think the point of existence for Women is to become Mothers, whereas Feminists tend to see that as selling out.
Fortunately Darwin tends to kill things like the Feminists meme.
Christians would say that's just God's will.
