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.

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.”
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.
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
