High Wire Walking





















I thought this was amazing ... and crazy.

If you haven't seen Academy Award Winning Man on Wire, it's a documentary featuring Philippe Petit's mind bending 45 minute walk between the World Trade Center Towers in 1974.

High wire walkers, including Pettit, hold a pole in their hand to take advantage of inertia (resistance to change in motion). The pole gives the tightrope walker a larger moment of inertia - meaning their angular motion will be less susceptible to change because the pole offsets any force the wire exerts on the walker - meaning they have less a chance of falling.

So, now that you know why high wire walkers hold a pole, watch Man on Wire ...

Philosophy and Neuroscience



Discover Magazine has summarized a study arguing that wisdom has a neurological component. Generally considered within the confines of philosophy, researchers pinpointed areas of the brain which, coupled with emotion and instinct, operate in a manner associated with wisdom.

Harvard Prof. Dr. George Vaillant attempts to answer this question after completing a 72 year study. Check out the study's summary in this video.

Short answer: happiness is not about 'me', but 'us'.

Hope for Lost Limbs




Salamanders have the amazing ability to regenerate a lost limb. Regeneration was assumed to occur because wound site cells would revert to 'pluripotent stem cell' status — allowing them to develop into many cell types and recreate the lost appendage — something adult human cells cannot do.

Nature recently published a study noting that salamanders' cells retain cell memory - that is they do not regrow from scratch. Rather than re-engineering human cells, it seems that the challenge is of coordinating already existing cells (like the salamander does) to reboot and regenerate. While a lot of work remains, the researchers now believe human limb regeneration may be an easier task than previously thought.

A Wandering Mind

















We all zone out, oftentimes at alarming rates. Discover Magazine recently ran an interesting article arguing that zoning out may not necessarily be a bad thing. Noting that most of the thoughts during zoning out deal with the future and much of deep thought occurs during these periods, Carl Zimmer posits that zoning out allows us to reach goals, but separates them based on their immediacy.

In related news, the Atlantic Monthly ran a feature article some time back entitled "Is Google Making Us Stupid?". Nicholas Carr argues that technological advancements have had a profound impact on how we think. Prior to the typewriter, we had much longer, drawn out sentences, but afterwords writing became much more terse. Today, the age of the internet and hypertext, has redefined 'short attention span' - think blog.

President Obama Notes Muslim Contributions to Science and Technology

While addressing Muslim countries in a key foreign policy speech in Cairo, President Obama noted the contributions of Islamic civilization to the advancement of science and technology, and also the interrelated history of Islam and America. Below is an excerpt; go here for the full transcript:
"As a student of history, I also know civilization's debt to Islam.  It was Islam -- at places like Al-Azhar -- that carried the light of learning through so many centuries, paving the way for Europe's Renaissance and Enlightenment.  It was innovation in Muslim communities -- it was innovation in Muslim communities that developed the order of algebra; our magnetic compass and tools of navigation; our mastery of pens and printing; our understanding of how disease spreads and how it can be healed.  Islamic culture has given us majestic arches and soaring spires; timeless poetry and cherished music; elegant calligraphy and places of peaceful contemplation.  And throughout history, Islam has demonstrated through words and deeds the possibilities of religious tolerance and racial equality.

I also know that Islam has always been a part of America's story.  The first nation to recognize my country was Morocco.  In signing the Treaty of Tripoli in 1796, our second President, John Adams, wrote, "The United States has in itself no character of enmity against the laws, religion or tranquility of Muslims."  And since our founding, American Muslims have enriched the United States.  They have fought in our wars, they have served in our government, they have stood for civil rights, they have started businesses, they have taught at our universities, they've excelled in our sports arenas, they've won Nobel Prizes, built our tallest building, and lit the Olympic Torch.  And when the first Muslim American was recently elected to Congress, he took the oath to defend our Constitution using the same Holy Koran that one of our Founding Fathers -- Thomas Jefferson -- kept in his personal library."

A Muslim Celebrates Earth Day

Earth Day should be a time for peace-loving people of all persuasions to share their views about the environment and the stewardship of natural resources. Like other great religious traditions, Islamic teachings have placed great emphasis on caring for the environment and for the careful husbandry of shared resources. Moderate, mainstream Muslims reject all forms of terror and violence, and care deeply about their world and its fragility and beauty. In celebration of Earth Day this month, I highlight here a few of the Islamic teachings that relate to these issues, and quote relevant passages from the Holy Qur’an, the sacred scriptures of Islam.

Islam acknowledges the existence of environmental pollution. The Qur’an describes how God demonstrates to humanity how their actions can destroy their surroundings: “Pollution has appeared on land and sea because of what men’s hands have wrought, that He may make them taste the fruit of some of their doings, so that they may turn back from evil.” (30:42).

Islam encourages careful land resource use.

Throughout the Quranic scriptures, we find references to the fact that natural resources are available only in finite quantities that must be carefully sustained lest they become wasted. Muslims are thus reminded of how all bounties are of a proper “measure”: “…He has created everything, and has determined its proper measure” (25:3). Muslims believe that the earth is first and foremost a shared resource that should benefit all of humankind, and that the harvesting of the natural bounties of the earth, such as fruits or crops, should be done with careful regard to not only present but future needs. The Qur’an reminds Muslims of this by stating: “…Eat of the fruit thereof when they bear fruit, and pay His due on the day of the harvest and exceed not the bounds. Surely, God loves not those who exceed the bounds” (6:142).

Islam enjoins believers to respect water resources.

This is also true of water resources, and Muslims are warned not to take supplies of water for granted and are also reminded of why water is a precious resource: “And We sent down water from the sky according to a measure, and We caused it to stay in the earth – and, surely, We have the power to take it away.” (23:19). Elsewhere it is stated:”He it is who sends down water from the clouds; out of it you have your drink, and there grow from it trees on which you pasture your cattle.” (16:11).

The Qur’an reminds Muslims of the ocean’s bounties.

There are many locations in the Qur’an where Muslims are enjoined to reflect upon the blessings they gain from the ocean, whether it is in the form of food within its depths, or from transport upon its waters: “And He it is Who has subjected to you the sea that you may eat therefrom fresh flesh and may take forth articles which you wear as ornaments. And thou seest the ships ploughing through it, that you may journey thereby  and that you may seek of His bounty in other ways and that you may be grateful.” (16:15)

Islam emphasizes stewardship of the Earth.

In many locations it is emphasized that humanity is to act as steward of the bounties it is given. According to Islam, the careful management of resources by humanity is a form of moral trial: “And He it is Who has made you successors of others on the earth and has exalted some of you over the others in degrees of rank, that He may try you by that which He has given you. Surely, thy Lord is quick in punishment; and surely He is Most Forgiving, Merciful.” (6:165).

Earth Day this month reminds us of the blessings we share on this planet, and how with one voice, we should reject fear-mongerers, terrorists, and those who seek to wreak havoc and create discord on our fragile planet, especially in the name of religion. After all, every religious tradition emphasizes the need to respect our planet. Regardless of our political, social or religious persuasions, we are all inside this sacred space and should try to protect it as best as we can.
