Theories of the Brane

String Theory is the dominant approach right now, and it has some success already, but the question is whether it will develop to the stage where we can actually solve problems that can be tested observationally.If we can’t bridge the gap between this ten dimensional theory and anything that we can observe, it will grind to halt.

In most versions of string theory, the extra dimensions above the normal three are all wrapped up very tightly, so that each point in our ordinary space is like a tightly wrapped origami in six dimensions. We see just three dimensions, the rest are invisible to us because they are wrapped up very tightly.

If you look at a needle, it looks like a one dimensional object from a long distance, but really it’s three dimensional.

Likewise, the extra dimensions could be seen if you looked at things very closely. Space on a very tiny scale is grainy and complicated–its smoothness is an illusion of the large scale.

That’s the conventional view in this string theories.

An idea which has become popular in the last two or three years is that not all extra dimensions are wrapped up–that there might be at least one extra dimension that exists on a large scale. Raman Sundrun and I (Lisa Randal) have developed this idea in our work on branes.

According to this theory, there could be other universes, perhaps separated from us by just a microscopic distance; however that distance is measured in some fourth spacial dimension, of which we are not aware.  Because we are imprisoned in our three dimension, we can’t directly detect these other universes.

Borge’s Map

“we now use the country itself, as its own map, and I assure you it does nearly as well”

Ubiquitous Sensing. The number of Internet-connected devices hit 8.7 billion in 2012. IP-enabled sensors are projected to exceed 50 billion by 2020. The number of sensors of all types is variously projected at between 1 trillion and 10 trillion between 2017 and 2025. The lower estimate translates to 140 sensors for every man, woman, and child on the planet.

Ubiquitous Connectivity. Mobile broadband subscriptions reached 2.3 billion in 2014—five times the number in 2008. The smartphone is the fastest-adopted technology ever; the biggest absolute growth is in India and China. At the end of 2014 there were nearly 7 billion mobile-cellular subscriptions globally—nearly one per person on Earth.

Convergent Data. The world’s production of data grew 2,000-fold between 2000 and 2012. Its stock of data is expected to double every two years; 99 percent of it is digitized and half has an IP address. This means that half of the world’s data can now be put together, at near-zero cost, to reveal patterns previously invisible. Half of the world’s data is already, technically, a single, universally accessible document.

How to rebuild our world from scratch using science: Lewis Dartnell at TED2015

We need More Science to Think about our life existence

Time for a thought experiment: Imagine for a moment that global catastrophe struck and you needed to rebuild the world. How would you do it? This is a topic that astrobiologist Lewis Dartnell researched in depth for his recent book, The Knowledge. At TED2015, he shares some of the highlights.

The are three important areas that have allowed civilization to progress, says Dartnell: food, fire and science.

Food. You could probably live for 55+ years on the canned and preserved foods in your local supermarket. But to rebuild civilization, you’ll need to farm enough wheat, rice and maize to feed yourself and at least 10 other people. Throughout history, this ratio has allowed cilviizations to progress and develop over time. To accelerate growth, you’ll want to add millstones to grind wheat. “The most important inventions othat have…

Spiritual

Each one of us choose on what to believe in our lives, and how further one is interested in dig into the truth, as the truth is an endless source of knowledge.

In the quest for mean and reason, life prepares many doubt situations for our self discovery. Most of these problems don’t even exist, as if faced by a life threatening situation, but all of them are reasonable while we’re living the moment, solve all of this equations makes sense till completion, then we’re ready for next level.

Some questions are deep and profound, but from some point on we’re not able to tell exactly what the truth is, how everything works. We have to guess, approximate, and believe in ours and others interpretations to understand and explain what we believe in order to create a sustainable explanation that allow us to consciously understand life.
We need some level of faith to survive.

It’s in the gap created by faith related questions like “where we came from”, “where are we going”, and “what’s the reason for our existence”, that religion and mysticism appears, simplifying complex things trough a notably wrong interpretation, sometimes blinding the truth, sometimes simply ignoring it.

The quest for God is individual and legitimate, is expressed by every single interaction of someone with the holy, sacred act of evolution, of discovery and  understanding the natural sciences. Seek for the truth is something divine, is the fuel propelling years and years of evolution, something inevitable as well as undeniable.

In the spiritual quest, knowledge is the drive, as one cannot believe what one cannot understand, but accept the fact that one doesn’t know everything (in fact anyone knows barely nothing), and after all, we’re looking for those who also seek the truth with that in mind: we’re in the middle of a journey that’ll never reach an end.
But we all need the truth, no room for mysticism.

The bottom line

Religion fills the gap where education and knowledge cannot be met.
With time, our society invariably evolves, we’re going to need less and less religious concepts and beliefs, science starts taking over this gap, explaining everything, filling the gap of knowledge, of understanding, the natural evolution.

Spiritual is the quest for the truth, always questioning, always aware that we’re far from the end, the absolute communion between men and nature.
In the relentless quest for spiritual awareness, remember to look at the stars and think that we, as individuals, know very little about the universe we live in.

Earth

Why is called Earth if it’s almost entirely covered by water?

Because it is mainly a huge rock that travels along the space, with lots of water in its surface.

There’s water in the ground, water in the air, coming from clouds that brings rain, water everywhere, but in its core, under the lava and magma and dust that shape our mother’s personality, Earth is a rock, and Water is the biggest living thing surviving in this huge, vast and hostile universe we live in.

Everything else that lives on earth depends on Water, in a way or another, to exist. Water is THE holy grail when thinking about life in the known world. No philosophy, no limits, no fun, no power without Water everyday of life. You need Water. You are made of water.

Water rules at the face of Mother Earth, and so we, Humans, think we’re in control of our lives. Our ecosystem is in danger, our existence is in danger. Life is spread everywhere over Mother Earth, from underground to skies, from the bottom of the ocean to the vast cities of reefs that keep the balance of life possible. We now have to sacrifice ourselves in order to give back what we’ve taken in excess from our planet. Humans are known to be super predators.

What if God, the Sun, solves to burn with more intense, and by mistake literally fries all the water in this rocky planet?
Taking away all life that exists only in this remote corner of the galaxy. Our water would get dry at the pan this world would become, making living miserable, unbearable and then impossible. There’s no water at Venus and Mars, and so there’s no conditions to life exist with current level of technology.

What if water gets scarce?
Becoming something to be traded at black markets at poor countries, making life extremely hard and restricted.

Maybe Mother Earth doesn’t care for Humans. They are here today, they have to make their way in order to survive. It was always like that.
Evolution is a must for everything here. There’s a whole ecosystem trying to survive on its back.

Water is probably the deep root of a soul that survives trying to make life viable for many different species along billions of years.

Water loves life. We owe her all our respect.

We were right in calling the planet Earth.
Water needs Earth to exist as much as everything else.
Earth doesn’t need anyone.
It is used to survive in the middle (figuratively) of a hostile universe in front of a gigantic, power star.
Some name it God, some name it Sun.

Earth grew up alone, a long, long time ago, and it’ll die some day, as well as Sun and Water.

Guess who’ll die first?

2014 in review

The WordPress.com stats helper monkeys prepared a 2014 annual report for this blog.

Here’s an excerpt:

A San Francisco cable car holds 60 people. This blog was viewed about 1,900 times in 2014. If it were a cable car, it would take about 32 trips to carry that many people.

Accrual

Accrual or accumulation of something is, in financial terms, the adding together of interest or different investment sources over a period of time.

It holds specific meanings in accounting, where it can refer to accounts on a balance sheet that represent liabilities and non-cash-based assets used in accrual-based accounting. These types of accounts include, among others, accounts payable, accounts receivable, goodwill, deferred tax liability and future interest expense.

For example, a company delivers a product to a customer who will pay for it 30 days later in the next fiscal year, which starts a week after the delivery.
The company recognizes the proceeds as a revenue in its current income statement still for the fiscal year of the delivery, even though it will get paid in cash during the following accounting period. The proceeds are also an accrued income (asset) on the balance sheet for the delivery fiscal year, but not for the next fiscal year when cash is received.

Similarly, a salesperson, who sold the product, earned a commission at the moment of sale (or delivery). The company will recognize the commission as an expense in its current income statement, even though the salesperson will actually get paid at the end of the following week in the next accounting period. The commission is also an accrued expense (liability) on thebalance sheet for the delivery period, but not for the next period when the commission (cash) is paid out to the salesperson.

Meet Mother Nature

This beautiful film made by Conservation International is part of a broader campaign, where nature shows its beauties in a personal matter, as the living creature it is.

Pay attention to the message and keep in mind Evolution is a path, not an end

Limits Nor Morality

David Ricardo’s insight into the price of land is nevertheless interesting: the “scarcity principle” on which he relied meant that certain prices might rise to very high level over many decades.

This could well be enough to destabilize entire societies. The price system plays a key role in coordinating the activities of millions of individuals –indeed, today, billions of individuals in the the global economy.

The problem is that the price system knows neither limits nor morality.

It would be a serious mistake to neglect the importance of the scarcity principle for understanding the global distribution of wealth in the twenty-first century.

To convince oneself of this, it is enough to replace the price of farmlands in Ricardo’s model to the price of urban real estate in major world capitals, or, alternatively, by the price of oil.

In both cases, if the trend over the period 1970-2010 is extrapolated to the period 2010-2050 or 2010-2100, the result is economic, social, and political disequilibria of considerable magnitude, not only between but  within countries– desequilibria that inevitably call to mind the Ricardian apocalypse.”
