OUTDOOR SOLAR LIGHTS

Solar Eclipses have always had Biblical Significance for example
Immediately after the tribulation of those days, the sun will be darkened and the moon will not give its light; the stars will fall from heaven and the powers of the heavens will be shaken." Matthew 24:29

"The sun shall be turned into darkness and the moon into blood, before the coming of the great and awesome day of the lord." Acts 2:20
what happened during the crucifixion? "Darkness covered the land." That is a solar eclipse and the stages of a solar eclipse varies, but can last a few hours. "The saints appearing to many," were simply the manifestation of spirits or ghosts from the other side of the grave.

On Friday, 2008 August 01, a total eclipse of the Sun is visible from within a narrow corridor that traverses half the Earth. Path of the Moon’s umbral shadow begins in Canada and extends across northern Greenland, the Arctic, Russia, Mongolia, and China.http://sunearth.gsfc.nasa.gov

Hooray! You’re back.

No, I don’t think that the solar eclipse will be a signal of the end times.

Asia will witness 21st century’s longest eclipse

BANGKOK – A swath starting in India and crossing Shanghai to southern Japan will be plunged into darkness for about five minutes Wednesday in the longest total solar eclipse that will happen this century.

Japan, which hasn’t seen a total eclipse for 46 years, is celebrating with fireworks. An astrologer in Myanmar has warned the eclipse is a sign of impending chaos. In India, some pregnant women have been told to stay indoors to follow a centuries-old tradition of avoiding the sun’s invisible rays.

The eclipse will appear first at dawn in India’s Gulf of Khambhat just north of the metropolis of Mumbai.

It will move east across India, Nepal, Myanmar, Bangladesh, Bhutan and China before hitting the Pacific. The eclipse will cross some southern Japanese islands and be last visible from land at Nikumaroro Island in the South Pacific nation of Kiribati. Elsewhere, a partial eclipse will be visible in much of Asia.

For astronomers, it will be a chance for a prolonged view of the sun’s corona, a white ring 600,000 miles (1 million kilometers) from the sun’s surface. The previous total eclipse, in August 2008, was two minutes and 27 seconds. This one will last 6 minutes and 39 seconds at its maximum point.

Solar scientist Lucie Green is aboard an American cruise ship heading for that point near the Japanese island of Iwo Jima, where the axis of the moon’s shadow will pass closest to earth.

Passengers paid $2,599 to $3,643 for the cruise run by Mayhugh Travel Inc., a California company that specializes in astronomy vacations, according to the company’s Web site.

"The corona has a temperature of 2 million degrees but we don’t know why it is so hot," said Green of University College London. "What we are going to look for are waves in the corona. … The waves might be producing the energy that heats the corona. That would mean we understand another piece of the science of the sun."

Scientists are hoping data from the eclipse will help explain solar flares and other structures of the sun and why they erupt, said Alphonse C. Sterling, a NASA astrophysicist who will be following the eclipse in China.

Man has been recording solar eclipses for 4,000 years, and even today they inspire a combination of fear, fascination and wonder.

One astrologer in Myanmar, also known as Burma, predicted in a magazine that the eclipse would trigger wars, instability and natural disasters for the next several months.

In India, hundreds of scientists have started arriving in the village of Taregna in Bihar state, where they hope to avoid the monsoon clouds hanging over much of the country.

Scientists plan to study atmospheric ionization, geomagnetism, asteroids, animal and avian behavior and the impact on microorganisms.

A team led by Dr R.K. Sinha of Patna University will study birds. "The researchers will observe whether they suddenly move back to their nests, sound differently and behave in an unusual manner due to sudden darkness," he said.

A travel agency in India is running a charter flight to watch the eclipse by air.

Some families have advised pregnant relatives to confine themselves to curtained rooms, following long-held fears that the invisible rays would harm the fetus and the baby born with disfigurations, birthmarks or a congenital defect.

"I’ve been told to lie straight on the bed with my eyes open and to chant prayers and verses from the Hindu holy texts during the eclipse," said Sonya Chadha, a New Delhi accountant who is seven months pregnant and plans to take the day off. "If even a tiny sliver of light falls on me, it could harm my child."

In Japan, where the last total eclipse happened in 1963, people are flocking to the small island of Yakushima, which is holding a a two-day festival with fireworks, dancing, grilled squid and cotton candy. The island’s 180 hotels are fully booked. A partial eclipse will be visible in Tokyo.

WOW!

As possible solar eclipse if the sun
as far as, so big. If there is no God
whether 2 things coincide man and a solar eclipse. In ancient times the false priests said that the earth is flat,
Copernicus and said if the land is not flat
hence there is no God, now think that’s flat
things do not happen, every thing has 3 directions, length breadth height and most ideal a round.

"Our concept of the establishment of peace, such that the distance of stars from
the land, a billion kilometers, and space consists of galaxies, but it is not because
God is the creator of the world. We represent this, fussiness and silly ideas,
because the star cluster of galaxies, not far away, as they say and show
astronomers, the same as the bow of the microscope will see, having dripped
iodine on capsule. The Earth does not rotate around its axis because it does not,
and earth does not revolve around sun because the sun revolves around the earth,
also stars and planets revolve around the earth, the stars and planets the same
subject, only their difference, appearance and distinction rotation time. Above the
stars of water, this is the same water, which is located in our seas and oceans,
slightly modified form, which we call Milky way, here’s an example from the Bible
-> 6 And God said, Let there be a firmament in the midst of the waters, and let
it divide the waters from the waters. 7 And God made the firmament, and divided
the waters which were under the firmament from the waters which were above the
firmament: and it was so. 8 And God called the firmament Heaven. And the
evening and the morning were the second day. 9 And God said, Let the waters
under the heaven be gathered together unto one place, and let the dry land appear:
and it was so. 14 And God said, Let there be lights in the firmament of the heaven
to divide the day from the night; and let them be for signs, and for seasons, and
for days, and years: 15 And let them be for lights in the firmament of the heaven
to give light upon the earth: and it was so. 16 And God made two great lights; the
greater light to rule the day, and the lesser light to rule the night: he made the stars
also. 17 And God set them in the firmament of the heaven to give light upon the
earth, 18 And to rule over the day and over the night, and to divide the light from

the darkness: and God saw that it was good. 19 And the evening and the morning
were the fourth day. Days establishment has no meaning in reality, because creator
and human life, it can create all in one day or one hour, or in one century, because
God is very strong and he created man. Celestial kingdom and allegoric looks,
written in the Bible, in Revelation, this our life and nature, because our land to be in
heaven, angels and Satan or the first snake, dragon and the devil, so we, the people
who choose or angel or Satan. In addition to God in the sky above the star, not who
is not. Jesus Christ was not in the past, if was, then wrote to the truth for us,
so-called apostles Jesus invented, because 12 Apostles, written in Revelation, it’s 12
sons of Israel who believe that my words, the whole world nations, I am Jesus Christ
and the Lamb in the book of Revelation. Lord God sent me to testify about it. The
sun revolves around the earth, as in a spiral path that is parallel to the equator,
climb and descend from the equator, to keep the same distance from land and
alters the season. "

The Lord God created man, created this book (Old Testament + Revelation)
also that people knew and recognized him. This book is prophetic, rather than
historical, which has written Lord God, during the creation of world, their own
hands, (because he can do it, because he created man) latest book of Revelation
(New Testament in fact fictitious) because the Bible, Old Testament, Consist of
different sorts of books (more than 1000 chapters and 43 headline). Of
Revelation John, is the same John, from the book Maccabees, which is the
smallest, and that I, as John and Jesus Christ, this is the same person. Book of
Maccabees penultimate book is the Bible, who do not have many Bibles. Byblos
is almost 4000 years of history of prophetic, advanced, and this prophetic
history is torn off sense between books of Revelation and the
Maccabees, nearly thirty years, these thirty years a clean sheet which my life

do your own homework kid….

okay im going to explain this question through a scenario.

Person A and person B are standing side by side on a linear racetrack, somwhere in space. Both are unaffected by gravity and both are at a complete rest, in space. Person A starts to accelerate, at the speed of light in 0 seconds, following a foward, linear path. At the exact same point of time, Person B shines a linear beam of light in the same direction. So Person A and the Light Beam is travelling side by side at the speed of light. Person A would expect to see the tip of the light beam traveling beside him at the same speed, but instead, he sees the light beam traveling a head him (1x the speed of light). How is this possible? It is because by traveling at the speed of light, Person A is actually traveling faster through time and thus he would see the lightbeam accelerated in time. And it is impossible for him to catch up with the beam, even if he increases his speed to 10x the speed of light, the light beam still seems to be travelling at the constant speed of light. This is what scientist say. And it is proven. we humans on earth are actually moving in space at fast speeds, by the movement of the earth, the solar system and the galaxy. SImilarly, other stars and galaxies are also moving at different speeds from each other. So we humans on earth would expect to see that light coming from this stars and galaxies to vary slightly in speed, however, the fact is that all the light coming from any direction, travels at the exact speed of light.

Now lets look again at the previous scenario. Person A and B standing side by side again. But this time, Both person A and B starts accelerating at the speed of light in 0 seconds(instantaneously). Person A would expect to see person B running at the same speed right beside him, and person B, vice versa. But according to the scientist, by travelling at the speed of light, person A travels faster through time, and thus should see that person B accelerated in time, ant thus moving faster and ahead of him. But how is this possible? Both of them are travelling at the same speed, and thus should be experiencing the same perspective of time.

So scenario 1 cant possibly be true, unless ofcorse, light is infinitely fast, and the only reason we see it traveling at the speed of light, is because that is the limits of time itself, Time just wont allow us to view the light traveling infinitely fast.

Im really confused here, HELP!
Thank you arainia, things are starting to make sense. It also means that my previous sources were bullshit.

Okay lets set up another scenario.
I am on planet earth. I want to visit my alien friends on a distant planet of a distant star, which is 10 lightyears away.

So i get on a spaceship that can accelerate to 99.999% of the speed of light in 0 seconds. I told my friends on earth that i would give them a call when i reach the alien planet. So the spaceship was launched on january 2010. My friends on earth saw the ship launch off at the speed of light towards the star. "For 10 years, they could look up with a telescope and see me flying through space. When they look closely, through a window in the cockpit, they observed that my movements were very very slow, almost frozen. 20 years has passed on earth, when my friends finally recieved a radio call from me.(it takes another 10 years for the radio message to reach from that planet to earth)." This were my friends observations.
But i observed things differently. As i lanched, It appeared to me that i was traveling FASTER THAN THE SPEED OF LIGHT. And it only took me 1 minute to reach the planet. This is because i was traveling very close to the speed of light and thus was moving way faster through time, compared to my friends on earth.

TRUE or FALSE?

Your explanation says that this is true. But if this is true, Imagine if instead of travelling at the 99.9999% of the speed of light, i traveled exactly at the speed of light, and The trip appeared to be instantaneous to me, Which means that i must have traveled INFINITELY FAST in my perspective.
True?
To zixin:

I do understand time dialation. For example, when a person travels at 99.999% of the speed of light, his clock ticks way slower when an observer who is stationary compares it with his own clock. However, the person traveling at the 99.999%the speed of light doesnt experience a slowmo effect, he experiences time normally.

If you actually read my second scenario carefully, you would see that i actually included the time dilation effect.

Lets go back to the scenario. Lets say that my ship travels exactly at the speed of light. My friends on earth would ofcorse see that my space ship is traveling at 3×10power8 meters per second. and that it takes the light 10 years to reach the planet. HOWEVER, because of time dilation, when I travel at the speed of light, my clock would appear to be frozen to an observer on earth. So for me, at that frozen time, which is an infinitely small amount of time, i would have traveled from earth to that planet, in other words, teleportation
You say that this is not true. You say that i would experience 10 years to reach that planet. If this is true, then theres no time dilation at all, since the people on earth sees that my spaceship takes exactly 10 years to reach the planet too.

So in conclusion, light travels infinitely fast, acording to its own perspective. THe only reason we see it traveling at 300 million meters per second is because of time dilation.

Somone prove me wrong

>Is light infinitely fast?

No. The speed of light is about 3*10^8 meters per second (a little less, actually). Furthermore, it appears to move at this speed for all observers, regardless of their own motion.

>both are at a complete rest, in space.

There isn’t really any such thing as ‘at rest’ in relativistic terms, since the motion of an object is relative to the positions of other objects. However, we can imagine that two people start more or less at rest relative to the rest of the Universe and each other.

>How is this possible? It is because by traveling at the speed of light, Person A is actually traveling faster through time and thus he would see the lightbeam accelerated in time.

No, you’ve got it backwards. They’re going SLOWER in time (infinitely slower in fact), which is why the light appears to move faster relative to them from their point of view than from Person B’s point of view. If time were running at a higher, but finite, speed for them, they would observe the light beam moving with them at the same speed precisely as we would expect, but this is not what happens.

>even if he increases his speed to 10x the speed of light

That too is impossible. He can never see anything else as moving faster than the speed of light, nor can anyone else see him omoving faster than the speed of light. As he puts more energy into his motion, he merely approaches the speed of light. If he is already moving at the speed of light (which is impossible) then his speed would not change because the energy would effectively be put towards accelerating an infinitely large mass. This is why you need an infinite amount of energy to actually reach the speed of light in the first place.

>Person A and B standing side by side again. But this time, Both person A and B starts accelerating at the speed of light in 0 seconds(instantaneously). Person A would expect to see person B running at the same speed right beside him, and person B, vice versa.

That is what they actually would see. Since their relative motion would be zero, each would also see the other’s relative motion as zero. Notice how we have a bit of a paradox here in that if you’re moving at the speed of light, light will appear to by you at the speed of light, but another object moving with you at the same speed has to have zero apparent speed. However, one would think that since Person B and light both move at the speed of light, the same behavior should be seen for both of them. This paradox serves to highlight the impossibility of actually reaching the speed of light in the first place.

>My friends on earth saw the ship launch off at the speed of light towards the star.

Or rather, at 99.999% of the speed of light, according to what you said before. There’s actually a very big difference; effectively, the difference between a finite quantity and an infinite quantity.

>As i lanched, It appeared to me that i was traveling FASTER THAN THE SPEED OF LIGHT. And it only took me 1 minute to reach the planet.

This isn’t entirely correct. Although you may well observe yourself reaching the planet in only one minute, you would never see anything going past you faster than the speed of light. This is because space also shrinks in your direction of motion. So for example, the people on Earth would see your spaceship much shorter from front to back than it is when it is stopped, and you would see the entire rest of the Universe squeezed down like a pancake in the direction of your motion. Your destination planet would not appear to approach you faster than the speed of light because you would appear to be only traversing a relatively small amount of space (no pun intended) during that one minute. Once you slowed down to a stop, space would appear to go back to normal and you could look back and see the distance of ten light years between you and your starting point.

>You say that i would experience 10 years to reach that planet. If this is true, then theres no time dilation at all, since the people on earth sees that my spaceship takes exactly 10 years to reach the planet too.

That’s correct.

>So in conclusion, light travels infinitely fast, acording to its own perspective.

That’s also correct, in a way. Although personally, I think it is more accurate simply to say that photons do not experience subjective time. In other words, from a photon’s point of view, its starting point and its ending point are the same point in space, and its starting time and ending time are the same instant. This is consistent with both the time and space dilation effects mentioned above.

The sun has a mass of 1.99*10′30 kg, and is moving in a circular orbit around the center of our galaxy, the Milky way, dragging the rest of the solar system behing it. The radius of the orbit is 2.3*10′4 light years(1 ly=9.5*10′15)and the sun has an angular speed of 1.1*10′-15 rad/s. What is the magnitude of the net force keeping the sun moving on this path?

F = m w^2 R = 1.99*10^30*(1.1*10^-15)^2*2.3*9.5*10^19 =
= 5.26*10^20 N

I have 12 nice solar charged LED path lights that I would like to hardwire. Someone posed a similar question on the former Google Answers but I still need a few things cleared up.

http://answers.google.com/answers/threadview/id/771491.html

I will wire all the lights in parallel. My solar lights only use 1 rechargeable AA battery each, so I am dealing with prob around 1.2V (I think the rechargeable batteries are 1.2V not 1.5V, but I will verify the voltage with a multimeter). I will find a DC adapter that is compatible. My questions are:

1. How many amps should the DC power supply be?
2. Is there a voltage drop to each light when wired in parallel?
3. Will the solar light furthest away from the power supply (at least 50ft) get enough/any power?
4. Does anyone foresee any longterm issues with this setup?

Thanks!

1. Allow at least 25 mA for each individual LED (count the LEDs in each lamp.
2 and 3. The voltage drop is along the length of the supply cable, so use a cable rated generously for the full output of the power supply.
4a. You may well have difficulty finding a 1.2 V supply, and so you might have to build your own.
4b. Damp-proofing is an issue, and in any case, as you are taking electricity outside, I would protect the power supply with an RCB.
