Exactly, actually you find that the world of finding out what happened can be very interesting. With data you try to deduce what happened, you avoid traps like “Correlation does not imply causation”


Anyways I will watch from the sidelines as you guys talk of esoteric stuff.

I am looking for a street way to explain to a kid why our DSTV satellites face the same direction even though the earth is spinning. He asked uncle is it that the DSTV stations are in heaven grin grin grin
Hahahahahahahahahahahahaha i love the curiousity of that little boy, help him more bro we may have a Nigrian eistein in him. . . anyway you can give him an example with sitting in a bus. .when the bus turns you still face front or anyside of the bus you were facing, because am sure when a bus turns it doesnt leave us and make us to now face the back of the bus instead of the front we wer facing. this is because of uniform speed between the body at rest inside the bus and the bus itself. .when the earth turns the dstv cables still facing the same direction because its just a body at rest inside the earth therefore turns at a uniform speed with the earth

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
basically, you are talking about temporal and spatial relocation without motion? Hmmm

No wahala na .... But why do some children tend to act after their dead father even when they never meet same alive.... I want to crudely think such is transferred from the father to the child maybe through gene/DNA or something ?
because those acts . . . are a result of genes.
You see, DNA can influence the way we act. But, the way we act cannot influence our DNA. So, while you may act like your father, if you change your character, your child won't resemble you. Instead, he will act like your father. You will be the odd one out in your generation. shocked

The human gene is encoded with physical features of an organism that can be transfered to the offspring. . . .but characteristics lik someone's behaviour is not a gene trait so that you can identify some certain behaviours in a son similar to what his father had can be just classified as coincidnce. . hitler and stelin were both serial killers, this behaviour they both share even when they are not related. . so similarity in personal behaviours has nothing to do with gene

why is the universe so massive?

can we ever explore our galaxy in a thousand years time?

When will we start investing money and time into theories that make faster than light travel possible?

the talk of infinite universes is so mind boggling

is our own universe ever going to contract?

brb.......
The universe is very small but because we human usually think we are big for our mind , we think the universe is so big .... But when you look from a plane or Helicopter , you would see how so small like baby cockroaches we human beings are and our deemed tallest skycrappers not to talk of our two storey building that will resemble anthills ...... little ants will also think the whole world end in her hole or Nigeria is borderless.

Exploring our galaxy in a thousand year time is possible in fact such feast may be achievable next year grin .... it depends strongly on effort of research and development in evolving tools that can Cruise successfully the different bodies in the galaxy in their different conditions. ....... I am always scared whenever I think we mankind will wake up one bigger trouble from the space one day maybe Animal or something out of this world that mankind as never seen before

Personally, I don't think the universe is infinite to an advanced Intelligence ..... The earth was once infinite to some folks sometimes ago.

Some larger forces can contract or expand our universe ...... we human are merely trying ..... Billions of events yet to be discovered.

Of course the science then are way more advanced than we think or make them out to be but just more crude than ours, we just developed more on what they know. .

E.g: The wheel, they invented the wheel for carts and chariots, we still use wheels today, tyres...

telescope, we also still use telescopes today of which one of the most remarkable the Hubble telescope .

so you see, its basically the same thing. . The scientific concept is the same just the portrayal differs
Why then did they abandon the water wheel? That would have been a very veritable tool for our agriculture especially now when agriculture's coming back in full swing..

I always think like your kidbro too when I was young .... I heard the earth is revolving and rotating and I asked myself why is our house still at her present location ..... I got to discovered through placing sand in a bowl then use a paper as our house placed in a section of the bowl then I rotate and revolve the bowl only to discover that my paper is still at her position alongside other properties but they are all rotating concurrently and proportionally thus Abuja won't be found in Lagos vice versa. grin ..... simple si.lly .........

everything in our galaxy revolve , thus the DSTV keep facing her satellite since they are revolving together.

The hanging gardens might have been built under a water fall or a rapid. From there, they could have tapped the water from above, instead of below.

that is a very good and plausible hypothesis and am sure that a water would also help make the garden more realistic and so have a better effect on queen Amyitis who nebuchadnezzer built it for cus she was missing the natural environment she was used to in her own land. . . But another question then in this is: Was there any waterfall within the city (babylonia was an enclosed city and a well walled one too) or maybe a waterfall near the royal palace too?

a question for archeological geologists. The place is all dried up naw, so there is no way for us "laymen" to figure out the past of the landscape. We can only assume.

sure thing lets wait for one to help us out. . . but in my own opinion there likely must not have been a waterfall within the city wall seeing how sun baked those lands were then or maybe it was much greener then than it turned out now. . archeological geologist, someone should help us out oohuh

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!
Hello!
I think air cycles are simply referred to as convection currents. But who knows? You might be the first to prove that air cycles exist.

Please i like d house to reason out dis questions with me: To wat extent is science objective taking into cognisance the object-subject dichotomy especially from d thought experiment of Erwin Schrödinger's cat in d box? Do we also have renowned classical female physicists? If not, y not? How true is d doctrine of realism especially since it doesn't depend on conscious observers? Let me also thank d brain behind this thread as it is going to go a long way in assisting my Doctoral thesis research in d area of philosophy of science. Pls i urge everyone in d house to take our discussions here seriously as we have mature minds here. Please if ua a child here, kindly go n play with ur toys outside. Thanks
Hello there. smiley
Well, this thread is meant for mature minds. We don't expect any "kids" here in the near future. I must confess, I cannot answer all your questions as I am not well versed in philosophy. Perhaps johnydon22 will have better luck?
The doctrine of realism is . . . I would not judge with a yardstick of truism but of effectiveness. As you know, realism is one side of a coin.the other being idealism.
Realists tend to view things with a factual and pragmatic approach. Hence, when things are unable to be quantified, they encounter problems. Idealists, on the other hand, view things "As they should be" and they tend to be more positive than realists. In life it is best to have a healthy mix of the two qualities. Using only realism, we can never achieve anything. Using only idealism, we will always plan to fail. So, I would say realism is half true.

There is one very notable female physicist. Marie Curie. There are not many other female physicists because physics require spatial reasoning. Something women are generally weak at. In physics, not much of observance is required but a lot of thinking is required. A physicist must be capable of real time simulation through imagination. The higher the ability to do this, the more successful a person can be in physics. However, since women are generally weak at this, they tend to shy away.

I hope this helped, smiley

Re: The Sciences Discussion Thread. by Nobody: 3:01am On Jun 22, 2015

Laughs . . . angry

I have seen everyone that agreed to be "in" on the project. Now, it is time to keep their promise.

Now, I have a topic.

I believe we all know that during the space of the last 150 years, the human race has increased roughly foiur inches in height and roughly twenty points in IQ. our life expectancy as also sky rocketed. With some countries now having Life expectancies of ninety and above. Infant mortality is also reducing drastically and in advanced countries, babies rarely die except they have serious fatal genetic diseases. Also, on average, people are becoming more and more attractive. Even without plastic surgery, in advanced countries, some of them just look angelic.

Now, here comes my question. One that I think will task the mind of all scientists in all fields.

WHERE IS THE LIMIT?

Is it possible that sometime in the future, humanity will be as tall as the na'vi in avatar?(ten feet) and the dumbest kid in a class will be smarter than adult Einstein and Newton combined? shocked
Could it be possible that sometime in the future, babies will never die? cry Or could humanity break the hundred and fifty year limit? angry

Will we be able to run faster than arrows? :oWe will be able to survive for longer periods than we currently do?
Will the girls from the future be so pretty that men of now would kill themselves to marry her? shocked
What is the limit to the improvements out species can experience before it degenerates or goes extinct?

If all of these are possible, then judging by the progression now, when will it happen? And is other anyway to accelerate it?

Patiently awaiting your thoughts on this. cool
Please don't disappoint.

lol the idea was to transport water from one point to another. . .tho the mechanics of these two are different i would vouch the water pump is more efficient. . . the water wheel would need a channel running all through the land to be irrigated so its water can move along, but the pump just needs a longer pipe

Let me try and tender my own opinions on this.
Is it possible that sometime in the future, humanity will be as tall as the na'vi in avatar?(ten feet) and the dumbest kid in a class will be smarter than adult Einstein and Newton combined? shocked
I think it can be possible since we know evolution is a slow and steady process but am not sure the average height will be up to 10feet, probably 6'8 or there about.
The intellectual capability of man has improved drastically these last few thousands of years and is expected to improve more drastically during the course of our evolutionary journey. . even other animals are getting smarter.. am sure in the nearest future we would have minds that will dwarf Einstein's with a wide margin but am sure not everyone could be that smart they must be impairment in some due to maybe slower genetic mutation.

Could it be possible that sometime in the future, babies will never die? cry Or could humanity break the hundred and fifty year limit? angry
I don't buy the 150 restriction there is no restriction by anything that determines the number of years humans should live. . its a biological phenomena to which every biological organism has its life span expectancy. . Many modern humans have exceeded this 150years life span like Algerian: Mubarak Rahmani Messe (1873- 2014) i also think then life spans of humans will improve in the near future like you postulated.
Its also ok to note that a Russian Billionaire is funding research on ways man can achieve immortality. . .Uuuhm fingers crossed, wouldn't like to live forever tho undecided

Will we be able to run faster than arrows? :oWe will be able to survive for longer periods than we currently do?
Sprinting ability in animals develop due to need for survival basically hunting, humans now are one of the animals that do not depend on basic hunting for survival, we are among the organisms that don't necessarily need to run for food but we are the only organisms to just run for fun (sports) so i doubt if our sprinting abilities will improve. . ancient homo sapiens are known to have ran longer distance which has decreased now due to the reduction in our dependency on this ability and more mechanized means of transportation which we expect to improve , so i postulate our running ability will decrease rather than improve with time.
Will the girls from the future be so pretty that men of now would kill themselves to marry her? shocked
Looks will improve all right but this will be on a more distributed basis so am sure humans has gone pass that stage of killing or fighting to get a mate. . so this improvement in looks and features will be a general improvement
What is the limit to the improvements out species can experience before it degenerates or goes extinct?
They can get to a stage where may be classified to be very different to what we are now but this may take millions of years to get to that drastic stage of evolutionary trend... If humans don't stop and have a rethink about what we are doing to this planet we live in, our species and many others wouldn't survive that long
If all of these are possible, then judging by the progression now, when will it happen? And is other anyway to accelerate it?
Evolution is a slow process or at least with what we think we know, so its likely to take a duration of millions of years. . . And yes accelerating this can be possible through Genetic engineering

I stand to disagree with u on this. I think the way we act can affect some stuff in our DNA by switching on/off of some genes....and there are some findings about silencer signals that re transferred 4rm somatic to sex cells b4 reproduction. Epigenetics explains it all.

So saying dat it is not possible isn't correct......
I'll welcome more facts from u
