Space-Time Cloak Possible, Could Make Events Disappear?

It’s no illusion: Science has found a way to make not just objects but entire events disappear, experts say.

According to new research by British physicists, it’s theoretically possible to create a material that can hide an entire bank heist from human eyes and surveillance cameras.

“The concepts are basically quite simple,” said Paul Kinsler, a physicist at Imperial College London, who created the idea with colleagues Martin McCall and Alberto Favaro.

Unlike invisibility cloaks—some of which have been made to work at very small scales—the event cloak would do more than bend light around an object.

Instead this cloak would use special materials filled with metallic arrays designed to adjust the speed of light passing through.

In theory, the cloak would slow down light coming into the robbery scene while the safecracker is at work. When the robbery is complete, the process would be reversed, with the slowed light now racing to catch back up.

If the “before” and “after” visions are seamlessly stitched together, there should be no visible trace that anything untoward has happened. One second there’s a closed safe, and the next second the safe has been emptied.

Event Cloak “Fun” but Challenging

The concept of an event cloak “is definitely an interesting idea and great fun,” said invisibility researcher Ulf Leonhardt, a physicist at the University of St. Andrews in the U.K. who wasn’t part of the study team.

Steve Cummer, a cloaking specialist at Duke University, calls the concept “interesting and exciting,” but he thinks that actually making such a cloak would be “really, really challenging.”

“All of the material parameters need to be time-varying in a very specific way,” Cummer said by email.

Currently, nobody knows how to do that except in fiber optics, in which the speed of a signal can be varied by a few percent by changing the intensity of the light.

“You can use an intense control beam to slow a signal down,” Kinsler said. In that way, an event occurring inside a fiber optic cable—such as an electrical signal moving from “on” to “off”—could be hidden from view.

“You would see the fiber, but some event occurring in the fiber could be cloaked,” he said. Such a proof of concept, he added, could be possible within a few years.

Powerful Laser Key to Cloaking?

There are still a few hitches to address, though, before attempting such an experiment, according to the University of St. Andrews’s Leonhardt.

For instance, being able to cloak an event lasting more than a few femtoseconds—one-millionth of a nanosecond—would require light from an immensely powerful laser, he said.

“The experiment is not entirely impossible, but it is at the limit of what one can do with present technology in an ordinary university laboratory,” Leonhardt said.

Study co-author Kinsler agrees that the fiber optics experiment is a technological stretch, but he counters that the problem can be eliminated by using a miles-long cable, as is routinely done in telecommunications.

“You can reduce the required power by using a longer fiber,” he said. That’s because the duration of the event you can hide depends on how long you can delay the light. A longer cable would allow you to get a longer delay from the same percentage slowdown, which would take less power.

Still, it may be a long while before police have anything to worry about—the materials needed for speeding and slowing light precisely enough for a bank heist have yet to be invented.

Thank Heaven for San Pedro

I guess San Pedro translates as Saint Peter, which is were I am writing from. Were it not for Starbucks I would be sitting at the Yum Yum Donuts getting fat on buttermilk donuts and crappy coffee or at the 7-11 a few blocks down the street responding to emails from my car.

Have you ever wondered how your life would be different were it not for the Starbucks, Coffee beans, Targets, Walmarts and all the other corporate stores? I can tell you, personally I would be fatter and hard pressed to find a place to pee and connect with the internet while on the road. So far as much as we hate them, these Starbucks and McDonalds of the world, they sure do make our life a heck of lot eaiser, which is why I am in San Pedro to make life easier for a few tenants at an apartment complex who seem to have a difficult time when it rains because thier roof leaks.

 

San Pedro is also home to very cool ports of call and a huge freight terminal that has as many overhead cranes as a park has trees. I am sure the things most of purchase during the holidays come through these here ports!

Long live leaky roofs, ports of call and my favorite – Starbucks.

That’s a few random things I am thankful for this Thanksgiving week. What are you thankful for besides the normal things we all seem to remember?

Thought for the day: Be Thankful for even the things we bitch about.

 

Contentment – Love the One You’re With.

I probably should not attempt to write about such an important part of Coming Up as late in the night as this but I feel  I should. You see a friend of mine earlier today made a comment about how he was with someone the other night while thinking of someone else. I give them tons of credit for being so honest with themselves and others and admitting it. Most of us would rather ignore it or hide it.

But we have all done it, and likely do it quite regularly. It’s only natural. But is it fair to ourselves and to the person we might be with? Not really, but each of is guilty of it.

It can be an old fling, an old relationship, spouse, a friend, anyone really. Perhaps someone we would just rather be with or can not get out of our mind. Whoever that other person may be, they are important enough in our mind – or heart – that we can’t stop thinking about them. Maybe it is just a fleeting thought and we forget them as fast as they came to mind, or maybe the thought of them overwhelms us so much we call the person we are with by the other’s name. That could be awkward!

Being present in the moment is not easy. We daydream, fantasize, and long for things beyond the moment and far from our grasp. Sometimes when these emotions and longings become so strong they can become dangerous. An addict will feign for his or her drug of choice stopping at nothing to get it. They will do things they later regret just to get their next fix. Likewise, if we desire something beyond our reach or beyond the moment to such a degree, it can harm our relationships and jeopardize what we already have.

Few things in and of themselves are dangerous in moderation. Even the most awesome elements, such as water and fire are moderately safe when contained in manageable amounts. Open the flood gates or turn up the flame – watch out. Those candle lights or droplets will turn in to a raging inferno or white water rapids.

Thoughts and reflections are lovely and can help inspire and motivate, but let them become obsessions and they will quickly become overwhelming compulsions that will distract you from the present and even cause you to throw away what you already have for something you think you need or want.

Being content with who are you are with regardless of the relationship., ie. a wife, a family member, a friend, a business partner or anyone, is an important part of being in the moment. It is only when we are in the moment that we are able to feel complete and satisfied. When we are complete and satisfied, we will find peace and experience happiness. That is a critical element to ‘Coming Up“.

Don’t bury thoughts of tomorrow or abandon your  dreams  but realize that the most important thing any of us has is what we have at this exact moment – life and thoughts for the one’s we are with.

Thought for the day: I will be present with the people/person  I am with but I will carefully chose the people I decide to spend my time with.

No Man is an Island

‘Coming Up” does not mean at the cost of other’s mistakes

..”For any man’s death deminishes me for I am apart of all mankinde”.    John Donne

On China’s Failures and Successes

China is well poised to overcome the US on so many levels. Despite this, We Americans need to refocus our energies on education, creativity and technological progress. Not only must we build better mousetraps and products, but we must also build better character in ourselves and our children. If we do this, we won’t need to fear China, but celebrate her successes and mourn when she fails as well.

well now you make no sense how could something like this happen if we keep Democrats the ones that shut down the Shuttle Program in power they will just shut down the rest of space exploration…. what needs to be done is Strip power from both parties…. Religion has nothing to do with this so.Vilic

I am no expert in Foreign relations but I am an expert in human behavior. We fear what we know little about. It’s easy to fear other nations and cultures that are not like ours, but does this help us and lift man as a species? No. It undermines all of us and eventually leads to our demise.  Instead of casting the stone at others consider your own shortcoming and ignorance. What are you doing to succeed? Are you blaming others and justifying your actions through hate and ignorance?

Today’s Thought of the day: I will embrace the differences in others and celebrate their successes and mourn their losses.   I will stand up for truth regardless if it is popular or not.

 

 

Good News

Today it is a little cold outside here in the Valley yet according to the latest news, the ice caps continue to melt at unprecedented rates and we have the hottest temperatures on record in the northern hemisphere. I also read that our nation is on the verge of economic collapse and bombs killed top officials in Syria earlier today, not to mention many others have been robbed, maimed, killed or robbed during random and/or planned crimes and accidents. There are many other depressing headlines but I think I will spare you the agony and move on to my point for the day which is basically, if you rely on the news to cheer you up, for get about it.

Happiness  comes from positive stimuli which for many of us will be the small things not the news we read about.

It’s the small things that make the difference in the world – not  the huge events.

So what are the small things?  The small things are the often overlooked stories or events that are difficult to find or which become overshadowed by the nuts and bolts of life. But if we dig a little, or tune down the TV or music we might find it and hear about them.  They can be a huge butterfly flying around your yard or a hummingbird hovering outside your window. They can be the new oranges on your tree that will be ready to eat in a few months or the figs you see growing on your baby fig tree.

They can also be the smile of neighbor or the dog barking in the back at a squirrel.

A phone call from a friend, an email from your kid who is away at school or a note from your bank telling you have more money than you thought you did.

As for Good News, here are a few headlines that I would consider ‘Good News” to help you with you mood adjustment:

If these are not enough for you, I suggest you just go outside and do some stretches and look up.

That’s what I just did and I feel better already.

Thought of the Day: Today I will go outside and stand under a tree.  It’s these small things (or big things if you have a big tree like me) that will make me rich and a little cooler when it’s hot.

 

 

Stillness

Consider the movement of river or stream. At times it is still and at other times is like a roaring lion. What’s interesting is that regardless of it’s appearance, the river holds the same energy.  What causes the river to increase it’s speed has more to do with the angle in which it is flowing and the opening in which it is flowing through.

Both these elements can be manipulated either naturally or through mechanical means. Does this mean that there is more water originating from the source? No. It’s still the same river.

Stillness affords us the opportunity to relax our force and to preserve it for the right occassion. Each of us has a life force that will run out – it is inevitable. Calming our mind and our spirits allows us to preserve it and to live a healthier more energetic life.

To enjoy the beauty of nature we must embrace the moment.

Thought for the Day: I will live for the moment and celebrate tomorrow when it arrives.

Finding Your Keys

TO FIND YOUR KEYS IT JUST MIGHT BE NECESSARY TO LOSE THEM

“…Our fate lies within us. We just have to be brave enough to find it.” From the Movie Brave

Not too long ago my girlfriend, Katie, and I took a weekend trip to Carlsbad, a little beach town a few miles North of San Diego and about 100 miles South of Los Angeles. It rained the entire trip.

The first night we were there we walked in the rain to a very nice restaurant a few blocks from our hotel.

The dinner was fantastic, the service was great and place was worthy of a return, which we did the following morning not because we wanted breakfast, but because we lost our keys and were unable to locate them in our room or in our bags.

We figured we must of left them there the night before and were hopeful we would find them when the owner greeted us at the door. Unfortunately, they were not there, or any where else we looked including the hotel lobby, the Mexican restaurant we visited for lunch the previous afternoon or inside the car.

Completely bummed out from our misfortune we decided that the only way out of the mess we were in was either to pay for a replacement set (which would have been extremely expensive as the style of keys we had were the new fangled smart type keys that were part robot, part personal computer), or hitch a ride back to our house where the spare was kept.

Fortunately for us we were able to get a ride from one our family members who was nice enough to make a trip from Long Beach and drive us back to my car located in Fullerton.

In the end we made it to Fullerton and then to Encino and back again to Carlsbad in time for dinner. By the time we were able to drive both cars from Carlsbad to home it was well into the late evening. To say the least, it was a very stressful and tiring day.

It was the following day when I received the call from Katie who telephoned me from her office to tell me she found her keys. They were right in her purse where she left them on that rainy, wet night in Carlsbad.

After we laughed and considered how silly we were to have not check the little pocket in her purse where they were placed, we moved on and promised ourselves we would both have spare keys nearby just in case we managed to make a similar mistake or if we lost our keys while on another holiday.

For as small as keys are they certainly are an important part of our lives. Without them we would not be able to enter our house, our office, start our car or unlock the many locks we have protecting our belongings.

When we have them, life is great. When we don’t, well life can get pretty chaotic.

We should look at our special qualities, talents and gifts as keys (formulas for happiness and success).

This morning I received a call from Katie who called to tell me she accidentaly left the same set of robot-keys on the hood of her car when she took off for work. She heard them fly off of the car as she sped off from one of the intersections down the street.

Frantic and stressed, and ready to get sick, she returned home to pick up the spares we keep and drove me down the block where I found the destroyed set laying thrown and splattered all over the street in one of the busiest intersections in the San Fernando Valley.

The bad news was the metal keys – the ones to the house and locks – where utterly destroyed, bent, broken and completely non-functional, but the good news was, the Robot-key – made of plastic – was a little scratched but otherwise okay. How that happened no one could say.

Once again we were forced to address the issue with keys and we confirmed we had extras just in case something like this happened again.

In every endeavor there is a key. An element or solution that will allow you to perform what ever tasks are necessary to accomplish your goal and mission.

Many of us will seek out the answers and the formulas to life’s mysteries by reaching to exotic places and trying to locate the keys far beyond where we may be.

In many instances the answers and secrets to a happy and successful life are closer than we think. We have them deep within us.

Unfortunately, because of the noises in our life and the chaos and company we keep (in Coming-up we will call them people, places and things), we loose sight of this or we are unable to discern them even when they are right in front of us or in us.

Thought of Today: Today I will slow down and be silent. I will look within myself to find happiness and my highest fate . It’s here that the secrets to my life and my success will be found.

Live – Learn and Love

Home is where I Am

I moved this passed weekend. Can’t say it was fun, but it is nice that I am out of that dusty old apartment.  I think I sneezed a zillion times. My new place is dust free thanks to my wonderful girlfriend. She loves a spotless place and has worked hard to make her house comfortable and tidy.

Sometimes it is a good idea to clean house. Now I am speaking allegorically now. Cleaning house allows us to evaluate what we have, what we want, what we can do without and what we really need.  Without cleaning up a bit and getting rid of the old junk, i.e., ideas, misconceptions, prejudices, baggage, etc., we can not move forward. It is also extremely difficult for us to self evaluate and adjust our thought processes to allow us to improve and move forward.

Our happiness and contentment depends on what we know we have and what we know we need in order to live productive, healthy loving lives.

Self reflection is critical to this process. Standing – or sitting  back looking at ourselves gives us a chance to get to know ourselves and to become more intimate with our inner person. It’s the inner-self who decides what we do, where we go, how we treat others and what we expect to see and achieve each day. This person could be trying to sabotage us, or challenge us. They could be trying to lift us up or tear us down. You will never know, until you take a moment and get to know them. Are they your friend or are they your enemy?  Strange huh? When you look at this inner-self as something or someone separate from yourself you can begin to hear what they saying or not saying better. Consider it someone who is ‘for you” or “against you”.  If they are for you, well, great, you can move up. If they are against you, well, watch out. You have lot’s of work to to get them over to your side, and as long as they are against you and not on your side, they will be trying to block you and stop you from moving ahead.

Thought of Today: Today I am here and in the moment. I am not in yesterday and I am not in tomorrow, but now. I will live my today one moment at a time and with one purpose, To be where I am.
