15 Reasons You Should be Drinking Lemon Water Every Morning

Samsung phones is it worth the wait.

Samsung Galaxy 8

Snapdragon 835 ARM chip and a USB Type-Cport. The iris scanner from the Note7 will

probably also make a comeback in the GS8. It’s

rumored Samsung will remove the 3.5mm

headphone jack, though. You can also expect it

to launch running Android Nougat with

Samsung’s TouchWiz interface, which isn’t bad

these days.

OnePlus 4

With Google’s discontinuation of the budget-

oriented Nexus flagships, OnePlus finds itself in

a very strong position. The OnePlus 3 and 3T

are powerful phones available for very

competitive prices; they are the best available in

the “budget flagship” category. That makes the

2017 OnePlus 4 something to look forward t

There have been some wildly successful phonereleased in 2016, as well as some monumental

flops. The question is, should you get one of

2016’s best Android phones or wait and see

what happens in 2017? Committing to a new

phone is a risk—there’s always something else

just around the corner. Maybe one of those

devices will be exactly what you want in a

phone. Before you make a purchase, you should

know what’s coming. These are the upcoming

Android phones you might want to wait on.

Samsung Galaxy S8

Samsung is just coming off the stunning

blunder that was the Galaxy Note7. This phone

launched with very positive reviews, but a

battery defect caused the phone to catch fire

much more often than other devices. Samsung

is looking to regain consumer trust with the

Galaxy S8, which will launch sometime in the

first half of 2017. It was originally believed to be

slated for an unveiling at Mobile World

Congress in late February, but that might be

pushed back now.

The Galaxy S8 will again use Samsung’s latest

Super AMOLED displays, but 2017 might be the

year flat Samsung phones start fading away.

The “Edge” variants (see above) have been

selling far better, so Samsung might just stick

with that design for both a small and large

variant of the phone. The resolution is unclear,

but a move to 4K is plausible considering

Samsung’s interest in virtual reality. If any

display manufacturer can make 4K AMOLED

displays viable on mobile, it’s Samsung.

It will most likely have a next-generation

Snapdragon 835 ARM chip and a USB Type-C

port. The iris scanner from the Note7 will

probably also make a comeback in the GS8. It’s

rumored Samsung will remove the 3.5mm

headphone jack, though. You can also expect it

to launch running Android Nougat with

Samsung’s TouchWiz interface, which isn’t bad

these days.

Largest scientific instrument everbuilt to prove Einstein’s theory of general relativity

https://speedoflightweb.files.wordpress.com/2016/12/screenshot_2016-04-25-09-48-32.png

Physicists hope the ambitious mission will allow
them to prove the existence of gravitational waves

–a phenomenon predicted in Einstein’s famous theory of general relativity and the last piece of his

theory still to be proved correct.

The mission, a collaboration between Nasa and the

European Space Agency, will use three spacecraft

flying in formation while orbiting the sun, with each

housing floating cubes of gold platinum.

Laser beams fired between the spacecraft will then

be used to measure minute changes in the

distance between each of the cubes, caused by the

weak waves of gravity that ripple out from

catastrophic events in deep space.

Einstein’s theory of general relativity predicted that

when large objects such as black holes collide,

ripples in space and time flow outwards. These

ripples are called gravitational waves.

A panel of international experts have now set out a

detailed plan for the mission and how it can be

used to reveal new insights about the universe

around us.Professor Jim Hough, an expert on gravitational

waves at Glasgow University and a member of the

committee that drew up the plans, said:

“Gravitational waves are the last piece of Einstein’s

theory of general relativity that has still to be

proved correct.

“They are produced when massive objects like

black holes or collapsed stars accelerate through

space, perhaps because they being pulled towards

another object with greater gravitational pull like a

massive black hole.

“Unfortunately we haven’t been able to detect them

yet because they are very weak. However, the new

experiments we are working on have great

potential to allow detection.”

Ground based attempts to detect gravitational

waves on Earth have so far been unsuccessful and

can only look for gravitational waves with relatively

high frequencies.

Scientists have already been able to prove a

number of predictions made by Einstein’s theory of

general relativity, including that light is bent by

gravity, that time can be warped by gravity and

that space and time can bend.

Einstein’s other theories including his most famous

formula E=mc 2 have also withstood scientific

testing.

The Laser Interferometer Space Antenna, or LISA

as the new space based mission is called, will be

able to detect gravitational waves of very low

frequencies due to the huge distance between the

three spacecraft. It will be the largest detector ever

built.

A smaller test mission called LISA Pathfinder,

which is being built by British engineers at space

company Astrium EADS and is due to be launched

next year, is to pave the way for the more

ambitious mission by demonstrating the

technology to be used to detect the waves.

Scientists have already begun building the

instruments that will be used in LISA itself, but it is

not expected to be launched before 2020.

They hope that once detected, gravitational waves

will be able to provide new information about the

universe that cannot currently be seen using

electromagnetic radiation such as light, radio

waves and X-rays.

Professor Sheila Rowan, who also studies

gravitational waves at Glasgow University, added:

“Black holes are so dense that no light or radiation

escapes from inside them.

“Gravitational waves from the warped spacetime

around black holes could give us new ways of

looking at them.

“We could also learn about the state of matter

inside collapsed stars.”

Dr Ralph Cordey, science and exploration business

development manager at Astrium UK who are

building LISA Pathfinder, said: “Trying to measure

cosmic events such as collapsing star systems or

the collision of massive black holes throughout our

universe requires ultra-high precision technology.

“The ultimate goal is to prove that this technology

works, before we attempt to put three spacecraft

into orbits at a distance of 5 million kilometres

from one another, connected only by a laser beam

that will measure their positions accurate to 40

millionths of a millionth of a metre.”

Home-made in China:Crazy DIY inventions, in pictures



What do you like doing in your spares time? Whatever your hobbies are, they are unlikely to be as exciting as these. Fromfully functioning submarines to tanks and homemade helicopters, here are some of the most inventive vehicles built by some men with slightly too much time in their hands.

Above, 50-year-old farmer Chen Lianxue with his homemade plane on the roof of his house in Qifu village of Pingliang, Gansu province. The plane

took Chen about 28,000 yuan (£2,900)

and over two years time to make, local media reported. Observant readers will

have noticed that Mr Lianxue’s craft

only has one wing.


Will the power of more than one solar panels when placed in series or parallel?

Assuming there are two or more solar panels being arranged either in series or parallel, and you are faced with the question will the power of these solar panels add up? Well I am sure that this article will help to answer your question.
Let,
P be the power of the panels.
V be the voltages of the panels.
I be the current of the panels.
With these parameters we can be able to solve this problem.
Now, assuming we take P= 300watts, V=12volts. With this, the current can be calculated as:
P=IV. Therefore I=P/V I=300/12 I=25A.
From the normal series and parallel connection of resistors,
Where for series connection the current is constant, while the voltage varies. .
And for parallel connection where the voltage is constant, while the current varies.

This is the same for solar panel and with these conditions the problem can be solved.

For the solar panels being arranged in series,

V_T= V_1+V_2+V_(3 )+⋯+V_n
Considering only two solar panels,
V_T=V_1+ V_2
V_T=12v+12v
V_T=24volts
Power for the two solar panels in series will be,
P=IV_T
With, I=25A and V_T=24V
P_T=25A×24V
P_T=600watts.
For the solar panels arranged in parallel,

I_T=I_1+ I_2+ I_3+⋯+I_N
Considering only two panels,
I_T= I_1+ I_2
I_T=25A+25A
I_T=50A
Power for the two solar panels in parallel will be,

P=IV_T
With, I_T=50A and V=12V
P_T=50A×12V
P_T=600watts.
In conclusion to the above calculations, it can be said that no matter how the panels are being placed or arranged (in series or parallel) the power will always remain the same
