I am in. My discipline is philosophy and i major in philosophy of science. By d way it was in d 17th century dat physics became an independent discipline. Prior to dat time, it was known as Natural Philosophy.
Welcome bro, Huge fan of philosophy here. . . It is well known that every branch of knowledge has its roots in philosophy even beliefs.

It was philosophy that started or proposed the questions. . and these questions gave birth to methods of answering them.

Religion and theology proposed answers that are meant to be believed without questions.…e.g: philosophy: Why does the rain fall? religion answers: a God did it.

Science approaches the question through study, research, observations and experiment and proposes answers that are always open to more study.
e.g: Philosophy: Why does it rain? scientific answer: Water circle

Not just physics bro, every branch of study was once a seed in the immerse depth of philosophical questions. . . No wonder is it Philo = Love & Sofia= wisdom. . . Love of wisdom

Is there anything like "air cycle"?..
Using the land and sea breeze as a starting point.
What happens there is the changing state of air temperature as it passes from land to the sea and vice versa.
But can we really prove that "air cycle" exists?..

Op didnt mention geography...I rep my fellow geographers!

For the programmers/engineers (or anyone who knows), help me with this question

How does mere codes alter the a micro controller function(s)

I understand that they are solid stated devices which comprises different logic units, and these gates have different functions. Each login unit/gate are made up of simpler semiconductors like transistors, diode, resistor caps, etc.. These semiconductors are made by doping silicon/germanium with a pent/ trivalent element.

ok, let's assume that a micro controller has been programmed to allows current to pass through on direction five seconds then switches off for 10seconds.
After reprogramming, it starts allowing current to go back and front for 3seconds, then makes it flow in only one direction for 5sec, after which it switches off for 15sec, then the cycle continues.

how is this possible
is the micro cotrl. changing it circulatory after reprogramming
or is it building new components inside itself
or is converting a transistor to a diode, diode to cap, resistor to inductor
or is it changing the chemistry of what's inside

sad Your little/huge help will be gladly appreciated

Thanks in advance.

anyone explain why we haven't gone back since then considering the
advancement in technology?
Chrisbenogor:

What would that mission achieve?
@Chrisbenogor it will achieve many things, let us wait for him to tell us why he thinks man can't go back to the moon and i will tell him man can and exactly when man is going back and why we haven't yet. .

Gravity distorts a lot of things. It distorts time, space(I.e distance and it gets worse the closer you are to it. E.g if you zoom past a black hole you might use about 70 years but to your own time its like an hour. Because when you get home all your kids are grandparents and you still look like you left. You see that kind of distortion? If you go into the black hole time and space(distance) will scatter. There will be nothing. No light no energy no physical laws. Everything will be infinitely nothing.
Wow! Now I get it.

Am so glad this thread opens. Ok guys lets get it going.

I stumbled on a quote made by my favourite scientist. Albert einstein the great. He said. Though i quote from a movie, that "IF YOU CAN RUN AS FAST AS TWICE THE SPEED OF LIGHT , YOU WILL BE ABLE TO TRAVEL BACK TO THE AGE and FUTURE" . he was quoted writing this theory when he was working on VORTEX TRAVEL. Vortex travel its a technology that can allow someone disappear to any place of choice jst like our juju for naija. From this theory many movies producers have developed some quite interesting movies e.g supernatural, the flash and mayb superman. If u had seen this movies lets say flash for eg. Barry allan ran as far as going back to the future. And at that point he travels faster than speed of light. You can check it up online and lets reason together on the possibilties. Enjoy guys

@ OP

Branes are based on M-theory origin of the universe. I don't so much agree with a cyclic process because it still left the origin of universe elusive. I support some parts of inflation, although how the Big Bang originated has not been observed(quantum physics can lay claims to how massive some fundamental particles can be at subatomic level). But, inflation is not so ambiguous as a theory because it has been observed that the universe is expanding rapidly by the effect of Dark Energy(DE) and this has been explained by notable astrophysicists and other scientists.

There is something you left out in your posts, the Nebulae. They are the building blocks in our universe - those galaxies clusters you see in the universe are birthed by them. In fact, they are where some of the most violent activities happen in the outer space.
I know about the Nebulae. I refrained from stating them above. However, I pointed out their existence by saying . . . mostly stars. It seems it is actually the other way around.

Mutations are caused by radiation.
Everyone of these guys in the electromagnetic spectrum radio wave (common carrier: mobile phones), infra red( not sure if this guy causes mutation though), visible light( consisting of the colours of rainbow which is the colour of white light), ultraviolet ( common carrier: the sun), xray (common carrier: xray for hospitals. Dats y it isn't good to take many xray scans), gamma ray (this bastard killed the couple that discovered it: the curry couple)

Mutations can result in physical disabilities like being born without legs, having more or less fingers etc.
Basically, any part on ur parent's DNA that didn't replicate a nose, leg, eye , etc parts, won't appear in you when you are born.
How to avoid mutation: pray to God.
Cause to can't avoid sun, or stop using phone etc of the aforementioned above(rays).
dude . . . ah, that is just one type of mutation.

shocked I will have to actively research in order to answer this. Although, it is a brilliant question. smiley

Aha!
After researching a bit, I found out that those codes we write are actually switches. Each time you write a code, each letter represents a switch in a transistor. So, while you are seeing letters, the computer is seeing what is beneath those letters. Binary.

Lol. . No bro, plans have been on since 2004 for another visit to the moon the operation is nicknamed Constellation due for 2020, You know its going to take that long?

Its because its no longer a few hours mission or something relative For one thing, the goal this time around is significantly expanded from last
time.

"This is much more than having flags and footsteps on the moon,"

NASA's Exploration Systems Mission Directorate Integration Office. "We're
going for a sustained human presence in space."
Rather than visit the moon for hours or days at most, Constellation
astronauts will embark on missions that could last months. They will need
new tools and technologies for living on the moon, and must construct semi-
permanent habitats on the lunar surface. Besides the challenge of designing
these systems, NASA must build a spaceship than can transport all the extra equipments and necessities needed

Ok before I run away, lemme say something.

If this thread degenerates to some high level stuff, people might get scared away. I was amazed recently in a book I am reading how interesting it is when basic science is explained in a very interesting way. So my challenge is pick something and explain it as simply as you can and in your own words.

Illustrations - analogies - something that passes the point.

Then one can build from this to explaining more complex things.

Guy, ure making mutation sound scary

Sorry 4 comin in late.....I commend d op and all d others that hav kept dis thread alive.

Talkin abt mutaton and natural selection.....I read all posts and u were all making sense....but I must add. 1st of all, not all mutatns are heritable. Mutation could be autosomal (those that affects other cell other than d sex cells, and re non heritable) or germline mutation (affects sex cells..ie cells that produce offsprings).

I read some1 say that a new species can't be formed through mutations.....m here to prove u wrong.......it is very possible.....rememba that a new species is formed when a mutated sp. gets so different from its parent sp. that interbreeding becomes impossible. It u nid a detailed explanation u let me knw (I don't enjoy typin long txts with my fone....but I'll do it)

Thirdly, recent research has shown that it is possible for phenotype (outward appearance) of an organisn to change without change in DNA sequence....this occurs wen switches come into play and switch off d expression of a particular gene.

This thread is just so great..........shalom!

Now, when DNA acquires a mistake in its gene programming, it has to be repaired immediately . . .usually, it gets repaired. But sometimes, it doesn't. Then the mutation becomes permanently engraved in and EVERY cell that comes from that cell will be similarly mutated. Even spermatozoa or the egg! And when this happens, during fertilization, this mutation is passed on to the offspring. cool
