The Sciences Discussion Thread. by Nobody: 3:46am On Jun 20, 2015 |
Hi there! Teempakguy here. ![]() So, I have been observing the science/technology section a lot recently . . . and I have to say, it focuses more on technology than science. I have also noticed that threads opened waste away, with about an average of two posts per thread. I think the problem here is a real life application the chicken egg problem. So, to solve it, the obvious solution, is to form a congregation of people interested in science in one place. Hence the creation of this thread. So, here is how things go, we are going to be talking on topics based on the natural sciences. Physics, chemistry, mathematics, biology, and of course, their basic applications. So, if you have a problem on any of those, try and post it here. In the mean time, if you stumble upon this thread and you don't have anything to add or subtract, please make sure you book space. ![]() I'm serious. Book space and tell us your area of specialization so that other people can mention you in their posts. Because, honestly, in this section, nobody knows anybody else. Meanwhile, I have some suggestions. If you want to give a complex mathematical expression, do not type it. Instead, write it on a paper or board and upload a photo of it. Same goes if you want to solve it. Or you could use mathlab android app. ![]() Any level is allowed. Whether it be primary school arithmetic ![]() ![]() You can just come by and drop interesting or random facts . . . like for instance, The Pythagoras' theorem is older than Pythagoras ![]() Or you can just tell us something yoiu observed in your daily life . . . for instance, why does a bar of soap form an hourglass figure after regular usage? You can also challenge popular views. For instance, since toilet floors are the most frequently cleaned in most houses, isn't it safer to eat food from a toilet floor than a dining room floor. Which gathers more bacteria than that of the toilet? There. I am finished. Oyah, come and occupy, the floor. Remember, small minds discuss people, average minds discuss events. And great minds discuss ideas. Which one are you? ![]() ![]() Cc.

The largest thing we know in science is a Brane. ![]() Branes contain universes. Universes contain clusters. But, Clusters are made of galaxies. Galaxies are made of stars . . . well, mostly stars. ![]() Stars have systems. Each star system has planets. ![]() Planets have . . . "spheres" our planet, Earth, has a biosphere This biosphere is made of living organisms. Like you and I . . . and goats. ![]() These organisms are made of organic systems. ![]() These systems are made up of organs. ![]() Organs are made of tissue. ![]() Tissue, is made of cells ![]() Cells are made up of organelles. Organelles . . . are made up of GIANT molecules! ![]() ![]() Molecules are made up of atoms . . . ![]() Now, atoms are made of subatomic particles . . . the electron, the protons, neutrons. ![]() ![]() Wait . . . even the neutron is made up of the electron and the proton. The proton is made of quarks! And quarks are made up of little, cute, superstrings. Gluons keep the atom core together and photons are the senior messengers that carry energy. ![]() ![]() ![]() We must not forget the higgs boson. This bulky guy gives all the other particles mass!! The electron is the negative guy that actually allows matter to occupy space!! Without that dude, matter would smash into each other and form huge black holes ![]() But nothing would be complete without the graviton. A really, really small particle which is really good at hiding. ![]() ![]() It allows you to play football, play "no bouncing" ![]() ![]() The universe is fascinating!! Each level of arrangements have a whole lot of juicy facts and patterns that can make your head swirl with excitement!! Which is why we study it with mathematics, physics, chemistry, and biology! And in science, our ultimate goal is to be able to explain every thing. To understand your universe. From the smallest string, to the largest Brane. In fact, EVERYTHING Cheers! 43 Likes 4 Shares |

menesheh:i'm sure there are people who are crazy about science here on NL. But they are outnumbered by uninterested persons! Plus they are not always online. (scientist don't have much time for social media). They can only come around once in a while. Nd when they do, only one or two topics might interest them. But i'm sure if this thread gets recognision, we would havee more of them coming online frequently to discuss ideas nd so on... Perhaps if the thread could get on the FP. @ op 5 Likes |

menesheh:hahahah ![]() But you forget, science originated from the black man nah. For example, we are the first to start learning simultaneous equations, quadratic equations, and geometric formulas. In we are the ones the invented Pythagoras theorem. ![]() We can still take back out glory. Don't you think? ![]() 4 Likes |

ELYMAXiimus:I like your signature. ![]() Welcome to the thread. You see, there is one thing about science, sometimes, YOU WILL run into problems you cannot solve. As Einstein said, one can never solve a problem with the same level of consciousness that created it. One sometimes needs help from others. And that is the difference, I think. Between us and technologically advanced countries. They actively search for help. We actively hide our work. I don't blame though, in Nigeria, plagiarism often goes unpunished. However, this is an online forum. Posting your problems and ideas here can actually prevent any form of plagiarism. It happens a lot in the literature section. Protect your work with copyright so that the fellow enthusiasts know not to copy you. Ever. Anyway, welcome. ![]() |

erico2k2: Menn fvck dude!! Am freaking smart in what i know and no one will ever boost of knowing everything. Even those ones you are pretty competent with will mess you up if you don't update to new developments in the field. Asking such a question didn't make me 10 yrs below anything. It is more of enhancing reason and exploring other field of learning. Ever near my field of study, i will blow your asss off if we are not of the same field.

menesheh:Hi there! I'm actually a teetotaler, so . . . if you have LA casera. ![]() I still don't understand why it was banned though. It has been here for decades and it had not killed anybody. Now it kills a few and the government quickly bans it without extensive research? That sounds wrong. And, typical of naija. ![]() Now, let's get to your question. ![]() Natural selection. This once highly controversial conjecture basically means that in life, two things happen constantly. 1. Things change. 2. The fittest survives. In every generation, there is a slight change in the genetic make up of organisms. For instance, some people are tall, others are short, it is a mixture of their parent's genes. Some people see more red than others, some are exceptionally brilliant, like everyone on this thread ![]() Now, having all these different characteristics, nature seeks to blend it. In fact, nature wants every member of each species to look and act exactly the same. ![]() This explains races . . . species . . . and a lot of impressive stuff. Individual members of species keep changing. And nature "tests" those changes to see which will stand the test of time. in the process, new species emerge. ![]() ![]() But one may ask, why? How? Why do these organisms change? What is going on here? Well, that brings us to your second concept. genetic mutation Imagine you are typing fast on your computer. And you make mistakes. Usually, you can just erase them. But what if you couldn't? ![]() ![]() Unfortunately, or not . . . that is what nature has to work with. During meiosis, DNA doesn't always get typed exactly as it should be. It makes mistakes . . . oversights . . . Typos! So this means everyone has numerous mistakes in their genetic make up. Which . . . they cannot erase. These mistakes are called genetic mutation and are the basis for natural selection because nature has to find a way to deal with these mistakes, so, it kind of thinks, which of these mistakes can we pass off as a new style? And that . . . is the best layman explanation I can offer. It is an oversimplification, but. I hope you got it. Feel free to ask any questions. If I can't answer them, there will be other experts. ![]() Cheers! 23 Likes 1 Share |

menesheh:Exactly. The Egyptian civilization started with mathematics. And yes, they did solve equations in their time. Along with the Babylonians, they are the backbone of quadratic and simultaneous equations. |

Teempakguy: Thanks menn. Awesome. As a non science-based person, wikipedia and other texts tends to give bogus and vague explanations that is rather confusing to a layman like me. Anything more deeper will still be appreciated. Cheer 1 Like |

menesheh:Wikipedia is an encyclopedia. And all encyclopedias are vague. ![]() Sorry for the long absence. I had a battery problem. So, you wanna go deep? Okay! ![]() Let see . . . mutation . . . well, ![]() Imagine yourself. You ask, what am I? What are you made of? Well, you are a complex construction. An organism. Now, you are made up of systems. Such as the muscular system or the digestive . . . which are in turn made up of organs . . . like the kidney, or the liver, which are ij turn, made of tissue. Cartilage for instance, or blood. And even these are made of cells. Which, are the smallest units of life. Beyond the cell, there is no life. But to understand mutation, we must go beyond. So, stay with me. ![]() In these cells, we have organelles. Like the golgi bodies . . . mitochondria . . . and most importantly, the nucleus. Which contain . . . . lolz, chromosomes. Beyond the chromosomes, what we have is just a set of instructions . . . which we will need! So, let's go! We have, in the very chromosomes, genes! And these genes are made up DNA! Bros, abeg just a little more patience. We are almost there. DNA is made up of four major bases. Which I will not mention here . . . now, you see, this DNA, can copy itself. I mean, literally copy itself and form identical copies of itself . . . . or not . . . . ![]() Remember what I said above about typos? You see, when a DNA tries to copy itself, it sometimes makes mistakes. These mistakes are called mutations. Sorry, battery low again! ![]() I will come back to finish. Watch out for part two. jaysniggs, thanks a lot. ![]() Be right back! ![]() 5 Likes |

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 ![]() ![]() ![]() Thanks in advance. 2 Likes |
