Do Bombs Really Tick?

“Actually, baggage handlers don’t worry about ticking ’cause modern bombs don’t tick. But when a suitcase vibrates, then they gotta call the police. Nine times out of ten: it’s an electric razor. But… every once in a while… it’s a dildo.”

— Airport Security Officer, Fight Club

Movies are there to entertain, so its understandable they don’t waste time on specifics and science. However, some movies invest so much time in developing a scifi premise or a character’s vast expertise in bomb making that it’s slightly insulting when they present us with something so amateur. (See our past article ‘are locks as easy to pick as in the movies?’ for more on movie realism.)

obviousbomb2This is older than television; if you look at animated cartoons from the early to mid 20th Century, one of the more common mayhem-related props is a bomb—black, bowling-ball-sized, with burning fuse stuck in the top, and possibly the word BOMB on it in big happy white letters.

On TV they always have blinking lights (red is a popular color), audible beepers and/or a timer counting down on them. Some bombs have all three. Older depictions have a loudly ticking alarm clock taped to a bundle of dynamite.

obvious bombIn reality, modern bombs that aren’t sanctioned by government are generally made not to be identified so wont tick, beep or otherwise indicate its true form. Military and construction bombs however are labeled to the extreme. Construction is due to health and safety, and military because as the majority are designed to explode on impact, labeling won’t affect their efficacy.

So to answer the question, no, bombs do not tick.

Shanghai metal manufactures the carbon steel strip for clockwork feeds which do indeed tick.

For Our French Readers: Le réseau routier des états unis est plus long que… la circonférence du soleil!

image

C’est déjà difficile pour l’esprit humain d imaginer de concevoir la taille de notre planète. Et celle du soleil alors ? Imaginons que la terre a la taille d un œil humain, celle du soleil a alors la taille d une balle aussi grande qu’ un humain. Maintenant, imagine l œil a cote de cette balle. Oui, le soleil est grand.

image

Maintenant, imagine la taille des états unis. C’est assez grand sur terre mais en rien comparable a la taille du soleil n est ce pas ? Et bien, au fond, si! Le réseau routier des états unis est aussi long que… une fois et demie la circumference du soleil! Appliqué a la densité de certain réseau routier comme le belge, cela ferait jusqu’ a… 10 fois la circonférence du soleil.

Mais revenons au réseau routier américain. Disons que nous voulons éviter que les automobilistes de tout les US ne sorte de la route. Nous devrions mettre, des deux cote de toutes les routes, des barrières de sécurité comme celle la

image

Ca nous ferait plus au moins 12 000 000 de kilomètre de ces barrières sur les routes américaines. Sachant que un km de ces barrières représente 26,35 mètre cube d acier, ou 204,2 tonnes, le Project entier représenterait la petite somme de 2 450 400 000 de tonnes d acier. Oui plus au moins deux milliard et demis de tonnes. Ca qui équivaut à un an et demi de la production mondiale. Il y a un siècle, à l’aube de la première guerre mondiale, cela aurait pris 34 ans eux industrie de produire une telle quantité. Cela vous donne une idée du progrès fait depuis. Et cela aurait été un sacre meilleur investissement que des armes et des canons qu’en pensez-vous ?

image

Nous, à Shanghai Metal Corporation, un des leader chinois du marche, notre capacité de production par an est 60 000 tonnes. Si il y a qui que ce soit dans l administration américaine intéressée à mettre des barrières de sécurité sur l ensemble des routes du territoire américain, nous serions très intéressé de faire un contrat pareil. 2,5 milliard de tonne vendue a 800$ par tonnes, cela ferait un modique contrat de 1600 milliard de $ s étalant, vu notre capacité de production actuelle, sur 40840 ans. Woaw cela nous plait, vous? A SMC, on aime voir les choses en grand, on aime voir les choses dans le long terme.

Move Along Airplanes – Submarines Overtake Travel

submarine1

China has moved a step closer to creating a supersonic submarine that could travel from Shanghai to San Francisco in less than two hours. Not much is known about the team’s progress because it is a military project, but the SCMP reports that Germany, Iran and the US are working on similar projects.

worldflags

The team from the Harbin Institute of Technology was inspired by a supersonic torpedo invented by the Soviet Union during the Cold War.

Water yields more friction on an object than air, which should mean that a submerged boat or weapon could never travel at the same speed as an airplane.

But the Soviet military figured out how to put a missile inside an air bubble to cheat this rule of science — a process known as ‘supercavitation’. They created the Shakval, a torpedo that could reach speeds of over 379 km/h, much faster than any other torpedo available.

submarinegraph

The Chinese team, led by engineering professor Li Fengchen, sought to apply the same process to a submarine by overcoming two central problems. The submarine would need to be launched at speeds of up to 100 km/h in order to generate the air bubble. It would also require very advanced steering because the ship’s rudder would be inside the bubble, not touching the water. The answer was found in the form of a manmade liquid membrane that would cover the submarine’s surface. The result is a vessel that could reach the speed of sound, crossing the entire Pacific Ocean in approximately 100 minutes. Once supercavitation is harnessed, it could be incorporated into any underwater activity.

Do Oil Discoveries Cause Conflict?

The conspiracy theorists will surely agree that oil and conflict is closely correlated – but do the statistics back it up? Economists have attempted to quantitative describe the relationship between discoveries of large oil fields and the probability of conflict.

war

 

Dube and Vargas studied this effect in Colombia and found that due to the concentration of oil profits being with the owners, extortion and kidnapping for ransom increased accordingly. This was described as a rapacity effect where it was in fact the money, not the oil that attracted conflicts.

colombia

Micheals found after conducting a worldwide regression that oil that it is actually the opposite –the increased wealth and opportunities from building the oil refinery actually decreased crime, as the potential criminals were less economically incentivized to commit crimes. The assumption that oil causes conflict stems from the anomaly that conflicts that arise due to suspected oil reserves rather than actual ones.

money

So in fact the building of oil drills and refineries can be beneficial to the surrounding areas, and the assumption they hurt an area was suggested to be untrue.

Shanghai Metal manufactures Salvage tools for oil drilling similar to those mentioned. To find out more, please visit our websiteLinkedInTwitter, Facebook and Instagram. Or you could try our new mobile app by scanning our QR code.
