Hi Guys, today I am going to post the second part of SPIDER-MAN CLIMBING SUIT (PART-2) If you have not read part one then click the link below https://rugber.blogspot.com/2020/05/Spider-man%20climb.html So I had told you that we can't make structures of that small, but we can really make structures that is small as few nanometers using nanotechnology . But the other problem is that we should cover over whole body with these small hairs, is this the end of our dreams ??? Not really, if we reduce the diameter of the structure to one nanometer. But we can't make structures of one nanometer (It might be possible in the future). There is a substance, whose diameter is only one nanometer - Carbon Nanotubes Therefore, if we used carbon nanotubes the total Van Der Waals Force will increase. But, this force is not enough to climb on walls. So, this is the end of our dreams.    I can't believe this, but what if we increase the force between two poralised atoms (Van Der Waals Force). ...

Hi Guys, today I am going to post about :- SPIDER-MAN CLIMBING SUIT I have already told you that we can climb using technology and also how do spiders climb wall. If you have not read it then click the link below   https://rugber.blogspot.com/2020/05/How%20do%20spiders%20crawl%20.html                                                           and https://rugber.blogspot.com/2020/05/Van%20Der%20Waals%20Force.html So if we make a gloves which has small hair like structures which is only a few nanometers thick, then there is a chance, that we could climb the wall like spider-man. The few nanometers thick hair will increase the surface area of contact, increasing the Van Der Waals force. This force will oppose the force of gravity, hence climbing the wall. But the problem is that we can't make structures (hairs) this small. And to oppose gravit...

Hi Guys, today I am going to post about :- THE VAN DER WAALS FORCES Van Der Waals force is a intermolecular force. You all might know that unlike charges attracts each other and like charges repels.   And you also know that atoms are generally electrically neutral.  See the image below   You can see there are two atoms labelled as atom-1 and atom-2 , when they are brought very close, the electrons in atom-1 tend to stay away from the electrons of atom-2 (Due to repulsion of like charges.) creating a poralised atom as shown in the image below Polarisation is a process in which atoms are brought near to each other for creating a positive and negative side of a atom. The attraction between the positive and negative side of 2 atoms is called Van Der Waals Force. I could not explain this concept very well, so watch the  below video   https://www.youtube.com/watch?v=7XiQ1PvsTQ8 Very Very Sorry. Comment down below if you want that I should again try to explain it to y...

Hi  Guys, today I am going to tell about :- HOW DO SPIDERS CLIMB WALL ? I have told you that there is still a chance to become SpiderMan using technology. So now, How does a spider climb the wall ? If we zoom into the spider's leg we can see small hair like structers called spatulae  which is only a few nanometers thick. These tiny hairs increases the area of contact of the spider's leg and the wall. All smooth surfaces are not really smooth in the microscopic level. When we touch a surface, there are minute gaps between the finger and the surface in the micropic level. Therefore these tiny hairs increases the surface area of contact. You might think that by increasing the surface area how can spider's climb wall. So to know the answer we should look at molecular forces, the Van Der Waals Force . I will tell you about the Van Der Waals force as soon as possible. THANK YOU 

Hi Guys, today  I am going to post about :- CAN SPIDER-MAN BE REAL ? All might have watched the spider-man movies, some might want to be spider-man, but is it even possible. You know that peter parker got his powers by a radioactive spider which bit him. But will this actually work... All spiders are generally radioactive, but it can't mutate our DNA, but even if we make a more radioacte spider it might not go as we have planned. We might get the climbing ability and spidey sense, but we can't produce web from our hands. By getting bit by these spiders may lead to death or any other diseases. So it is not safe, therefore we can't become spider-man through a radioactive spider. But is there no other way.... There is another way to become spider-man by technology. A research team has even made a material that can help us climb the wall as shown below but there are many problems to this material, we can...
