Human Limit - Vertical Leap

-

A lot of people said that Michael Jordan could stay in the air for 2 to 3 seconds.

This means that his hang time in the air is 2 - 3 seconds.

After doing some research about this,

This is almost impossible for a normal human.


To generate a second of hang time in the air, you need to jump about 50" above the ground!

Therefore, for a 2 to 3 seconds hang time, you would need to jump about 150"! Which is about 3.8 meter.


Some people think that MJ was not only jumping vertically, but also horizontally, which was a parabola shape. Wouldn't it increases the hang time?

If you have a little knowledge in Physics, you would know the time for an object that were thrown diagonally (about 45 degree vertical) to the air would increases the hang time, the higher the horizontal (x-axis) force, the longer the object fly in the air. However, it is not exactly what we are talking about here. The hang time is extended not because of the vertical leap, but it is because of the horizontal force. For MJ's case, his horizontal force, of course would increased his hang time, but definitely, it would not be more than a 0.2 seconds.

Gravity is the main reason here. You will generally be able to impart more force to a lesser mass on the initial leap (thereby generating a higher vertical leap), but once you're in the air, the effect of gravity is the same whether you're 160 pounds or 260 pounds. In other words, two people, one 100 pounds heavier than the other, will remain in the air the same amount of time assuming they have an equal vertical leap.

Therefore, if he is able to jump about 40" (100+ cm) which could produce about 0.8 seconds hang time, his total hang time would be around 1 second.

This kind of calculation has already not exactly ONE second, how about THREE second in the air?

However, MJ did a real good job when he dunked.

He misled most of us by holding his ball when he jumped, and dunked it when he was dropping or when his vertical force been overtaken by gravity force.
Other than that, after he dunked, he hold the hoop for about 0.5 second which bought him some hang time, then he tucked his leg up so that his dropping time increases for about 0.3 seconds, so in total, it was about a 2 seconds hang time from his initial leap until he landed.

I was amazed by dunking, therefore, I went through some research and this is what I found.

Hanging in the air for 3 seconds?
Practically, almost impossible for human. Current highest NBA players hang time is about 1 second!

and this record was set by MJ who jumped 48" (about 122 cm) in the air.

My TOP 10 Manga!

-


Rank #10 Bleach



I started reading Bleach a year before I came US. I started reading comic when I was 7 years old, therefore, Bleach is consider late comer in my comic life. This comic attracted me by making the "Shinigami" as the main character. The main character of this comic is Ichigo Kurosaki. I rank it at tenth place because this manga started real good but it is kinda messy and not organize these 2 years. However, among 60+ manga that I have read or been reading, it is worth to rank it at tenth place.


Rank #9 Naruto


Naruto is a manga that accompanied me since 1999. I was only Form 3 that time. I read it since Volume 4 till Volume 50+. Think about it, it is about 10 years time! This manga is talking about ninja. It was pretty special and it started real well. It was really a great comic and caught a lot of fans during the year 2000 to 2006. It was one of the top manga in Japan. However, the story got a little too slow now. I still like it a lot, but not as much as I liked it 5 years ago! I hope it will turn better and hope that the coming episodes would have some changes~ The main character of this manga is Naruto Uzumaki~

Rank # 8 Death Note


Death Note is one of the comic that base on story instead of fighting or fancy drawing. I love the story line of this manga and love it since I read the first volume. I didn't know about this manga but I was attracted by the Author. The Author of Death Note was the author of another manga which I like a lot. One of the reasons I bought the first volume of it without asking any friends or checking it's review from the internet was because of the author. After reading the first volume, I was attracted and looking forward for the second volume. It didn't disappoint me, it had a real good start, and it also ended nicely. It is one of the best manga (Story Base) that all the manga lovers should not miss!



Rank #7
棋灵王 (HikaruNoGo)

This manga is another story base manga. This is the manga that I have mentioned above which is the same author as Death Note. The manga main plot is talking about Board Game which is a very popular game in Japan. I couldn't imagine that I was actually attracted by this comic when I was 15 years old. This is because this manga is really good, and you would be suprised by it by reading it yourself. Even though it is talking about board game, it was not boring at all. Read it, and you will find that it is worth to use your time on it!









Rank # 6 GTO

Great Teacher Onizuka!! I believe most of the manga lovers know about this manga!! This is one of the funniest and interesting manga I had ever read. I knew Onizuka from another manga called 湘南纯爱组 which is drawn by the same author, and the story for that manga was talking about Onizuka high school life. I like that manga a lot but probably it can only be fitted in top 20 compare to these mangas. GTO was drawing all my attention to him when it just came out. Especially for that time, I think it is good timing as well. This is because I was about 16 years old when I started reading this manga, which started to know those dirty jokes and stuffs. I found that was really great and it attracted me to keep on buying the comic till the last volume of it!


Rank #5 新功夫旋风儿- 柔道篇(Shin Kotaro Makaritoru - Judo Hen)

This is one of the best manga of ALL time. This is actually the second version, and there is a third version, which name as Shin Kotaro Makaritoru - L. It is as good as this version BUT, the Author is sick and can't continue drawing the rest of the episodes! If he was able to draw, the latest version of it would definitely be my top ten manga. Hope the Author recover soon so that we will have chance to read more of his manga!!

This manga is talking about JUDO. The main character Shin Kotaro is really funny yet, he is really strong in the story. I like the way the author draw the character and the way he draw the character expression of every single thing. This is a typical fighting manga but with a lof of funny scences in it! Worth to read~ :)





Rank #4 Hareluya Boy

Plot -

Hibino Hareluya is a delinquent teenager who is tough and loves to pack a punch. His father is none other than the almighty God who does not approve very well of his son's rebellious acts. Disappointed in Hareluya's lack of responsibility, his father sends him to Earth as a normal high school student, stripped of his powers. Posing as a local priest, God keeps an eye on his son's adventures as Haleluya rights wrongs around the school with two-fisted justice, Love tattooed across the knuckles of each hand.
This manga might not be the best fighting manga because the main character never lost. However, it was so good to me because it was really interesting and the story line was pretty well line up. Isn't it good to see the main character undefeatable? it might not makes sense, but THIS is MANGA!!!! XD


Rank #3 Dragon Ball

Plot -

A monkey-tailed boy named Goku is found by an old martial arts expert who raises him as his grandson. One day Goku meets a girl named Bulma and together they go on a quest to retrieve the seven Dragon Balls, mythical objects that can summon a dragon who will grant any wish. Along the way, they meet and befriend a plethora of martial artists. They also undergo rigorous training regimes and educational programs in order to fight in the World Martial Arts Tournament, a tournament in which the most powerful fighters in the world compete. Outside the tournaments, Goku faces diverse villains such as Emperor Pilaf, the Red Ribbon Army, a demon known as Piccolo Daimao and his offspring.

As a young adult, Goku meets his older brother, Raditz, who tells him that they come from a race of extraterrestrials called Saiyans. The Saiyans had sent Goku to Earth to destroy it, but his ship crashes upon arrival. Goku fell into a deep ravine and lost all memory of his mission. Goku refuses to help Raditz continue the mission, after which he begins to encounter others who want to battle him, such as the Saiyan prince Vegeta. He also encounters Frieza, who is considered to be one of the strongest beings in the universe, after which Goku begins training his first child, Son Gohan, to be his successor. Years later, a group of soldiers from the Red Ribbon army known as androids appear to kill Goku. Another android, Cell, absorbs Androids #17 and #18 from the Red Ribbon army to increase his power, then fights Goku and Gohan, resulting in the former's death. Goku decides to stay dead for seven years to train in the Other World. When he returns, he is drawn into a battle for the universe against an extraterrestrial named Majin Buu. Joined by Vegeta and Gohan, the evil half of Buu is destroyed and the Good Buu (Mr. Buu) settles down with them. Ten years later at a martial arts tournament, Goku meets evil Buu's human reincarnation, Uub. At the end of the series, Goku takes Uub away on a journey to train him as another successor.

I believe that Dragon Ball is a legend! It was so good, and the best of it was special! No other manga thought of using the way Dragon Ball expressed itself to the readers. I will like to say, This manga is Unique!


Rank #2 Slam Dunk

Plot -

Slam Dunk centers around Hanamichi Sakuragi, who starts as a delinquent outcast, becoming the leader of a gang. Hanamichi, being very unpopular with girls, has been rejected by them fifty times. Yet, he finds out that Haruko Akagi is the girl of his dreams, and is happy when she's not scared of him like all the other girls he has asked out.

Haruko Akagi, who recognizes Hanamichi's athleticism, introduces him to the Shohoku basketball team. Hanamichi was reluctant to join the team at first because he had no previous background in any sports and thought that basketball was a game for losers (also because the fiftieth girl rejected him for a basketball player). Sakuragi, despite his immaturity and hot temper, proves to be a natural athlete with potential and joins the team in order to impress Haruko and prove that he is worthy of her. Kaede Rukawa — Sakuragi's bitter rival (both on the basketball court and love, even when Rukawa doesn't acknowledge Haruko's crush on him), the star rookie and a "girl magnet" - joins the team at the same time. Hisashi Mitsui, an ex-junior high school MVP, and Ryota Miyagi , a short but fast player, both also rejoin the team and together these four struggle to complete team captain Takenori Akagi's dream of making Shohoku the national champion. Together, these misfits gain publicity and the once little known Shohoku basketball team becomes an all-star contender in Japan.

I have no right to comment on this comic. It is the best manga all time!


Rank #1 One Piece


Plot -

A boy named Monkey D. Luffy, inspired by his childhood hero "Red-Haired" Shanks, sets out on a journey to find One Piece,

the legendary treasure of the King of the Pirates, Gold Roger. To accomplish this, he must reach the end of the most deadly and dangerous ocean: The Grand Line.

Luffy captains the Straw Hat Pirates first through the sea of East Blue and then through the Grand Line. He follows the path of the deceased King of the Pirates, Gold Roger, from island to island on his way to the great treasure One Piece. On his way his crew grows to have a swordsman, a navigator, a sniper, a cook, a doctor, an archaeologist, a shipwright, and a musician.

During the course of the story, the crew contend with both other less moral pirate crews and the Navy. The latter are the subordinates of the World Government, who apparently seek justice by ending the Golden Age of Pirates. Many background story elements involve the delicate balance of power between the World Government and the world's most powerful pirate crews.



Setting -


The fictional world of One Piece is covered by two vast oceans, which are divided by a massive mountain range called Red Line. The Grand Line , a sea that runs perpendicular to the Red Line, further divides them into four seas: North Blue, East Blue, West Blue and South Blue. Surrounding the Grand line are two regions called calm belts, which experience almost no wind and ocean currents and are breeding ground for the huge sea creatures called sea kings ("neptunians" in the English manga), because of which the calm belts are very effective barriers for those trying to enter the Grand Line. While the navy ships, using sea stone to mask their presence, can simply pass through, most have to use the canal system of Reverse Mountain , a mountain at the first intersection of the Grand Line and the Red Line. Sea water from each of the four seas runs up that mountain and merges at the top to flow down a fifth canal and into the first half of the Grand Line. The second half of the Grand Line, beyond the second intersection with the Red Line, is also known as the New World.

A Log Pose

The currents and weather on the Grand Line's open sea are extremely unpredictable, while as in the vicinity of islands the climate is stable. What makes it even harder to navigate is the fact that normal compasses do not work there. A special compass called a log pose must be used. The log pose works by locking on to one island's magnetic field and then locking on to another island's magnetic field. The time for it to set depends on the island. This process can be bypassed by obtaining an eternal pose, a log pose variation that is permanently set to a specific island and never changes.

The world of One Piece is filled with anachronisms, like the transponder snails, lit. electric transmission bug), snail-like animals that can be attached to electric equipment and function as rotary phones, fax machines, surveillance cameras, and similar devices. Dials , the of certain sky-dwelling animals can be used to store wind, sound, images, heat, and the like and have various applications.

Devil fruit are a type of fruit which when eaten confer a power on the eater. There are three categories of devil fruit. Zoan fruits allow the user to fully and partially transform into a specific animal. Logia fruits give control over and allow the user "to change their living body structure into the powers of nature". Paramecia (called "Paramythia" in the 4Kids dub) is a catch-all category for fruits that give the user superhuman abilities. Devil fruit users cannot swim. When even partially submerged in water, they lose all of their strength and powers.

(www.wikipedia.org)

This is the number one manga for me! It has made me Laugh, Angry, Sad, Cry and happy! There is no other manga can substitute this! The story line is awesome, it is all well plan, and the best is, after more than 500+ chapters, it is still good, and I still feel so excited everytime I read it. It is so hard to just maintain the story, it not only maintain the good story, it is actually becoming better and better!! GREAT manga!! :)

Kimbo Slice..

-

I dont think he is real good fighter at all..

Watching him fighting with amateur, he was just bullying them. He showed real bad attitude, lack of sportsmanship.

Even tho he won almost all his street fights, but he got his ass kicked in UFC!

4th fight in UFC, he got knock out in less than 10 sec..

zzz

Can you believe that! HAHA~

This is what I have been looking for recently.. other than looking for a job.. my other work is watching drama, variety show, reading comic, random stuffs from the internet and Youtube..
