How many children Ollie has?

How many children Ollie has?

The next task is a good example of a network-based logical problem. There are three logically possible answers and the problem goes like this: Ollie has four daughters, and each daughter has a brother. How many children that man has? The first two are straight logically inferred, and the third one, well there is a possibility that Ollie has made them with different women.

1) Zero, Ollie is a man, and men cannot give birth. In this case, the logic goes, that Ollie should give birth for those children himself. So the answer would be 0.

2) Five, that means that those four daughters have one brother. And that means Ollie has five children. In this case, the children are Ollie's dependents, and he is responsible for their needs.

3) Eight, in this case, every daughter has a boy couple, but that thing is a logically little bit limp. And that means that in this case, the question or tip in question should go "every daughter has four brothers".

The numbers six and seven are not suitable because that means that Ollie has two or three sons. In that case, the question or the tip in question should go "Ollie has four daughters and each daughter has two (or three), brothers. So this is one of the most fantastic logical thinking assignment, what I ever have seen.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Could this be the thing, that some people don't want you to know about zombies?

Could this be the thing, that some people don't want you to know about zombies? The simplest way to control zombies, which are made by using tetrodotoxin, which is called "zombie poison" is to use the automatic dispenser, which is normally used in diabetes treatment. In this case, the dispenser would be loaded by using tetrodotoxin. If the level of this poison is right, the person would be totally under the control of other people. And if the system cannot detect this poison there is a possibility to make the laboratory experiment when the staff will follow the decrease of the tetrodotoxin, and then the system can use a simple clock, which will inject poison to the body of a victim after a certain time. This would be an effective tool in the hands of military and counter-terror operators. Those zombies can be captured enemy operators, who will send back, and then they just kill their ex-partners. By using genetically engineered bacteria could be possible to create t...

The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like.

. The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like. Above is the image of the nano-submarine. There is introduced an idea, that this kind of system would equip with living neurons, which makes it like some kind of artificial bug or mosquito. The idea is that the robot can take the nutrient by using the robot tube, which acts like a proboscis. The neurons can get nutrients and the rest of the machine can use small fuel cells or the energy to that system can deliver by using the radio waves. Futurologists are thinking about the ideas, what the hybridization of the neurons and machine would look like? Could the hyper-technical civilization look like the group of midget submarines? Those submarines might take nutrients for the neurons, what is living in them. The purpose of the midget submarines, which might be size less than a couple of millimeters would maximize the survivability of the neurons. One of the most intere...
