Does Lightning Kill fishes or Marine Creatures in ocean?

  • Do you ever got doubt about what happens if lightning strikes ocean? 

  • How Lightning Strikes Affect Marine Creatures?

  • Why Doesn't Lightning Strike Deeper into the Ocean?  

     -->Our view would the entire ocean would experience the shock as water is good conductor of electricity but the fact is.....

    There are plenty of stories of people getting hit by lightning but few about lightning fried fish. Find out whether lighting strikes hit fish and why or why not.
Conventional wisdom says to get out of the water when a storm approaches. However, while people are scrambling for shore, the fish and whales of the sea stay right in the water. 
 Considering sea creatures still exist in the ocean it would seem they are unaffected by lightning. This is only mostly true and a look at how lightning and the ocean work will explain whether or not lightning strikes kill fish.

How Often Does Lightning Hit the Ocean?

SCIENTISTS CAN HACK OUR BRAIN AND EXTRACT OUR PERSONAL INFORMATION??

Scientists can hack our minds  with cheap EEG gear 

Inexpensive brain-computer interfaces could be used maliciously to obtain private information such as PINs stored in one's memory, according to researchers. 

  • Are you ready for brain spyware?
  • Are the deepest secrets of your mind safe? 
  • Could thieves trick you into revealing your bank card PIN or computer passwords just by thinking about them?
-->Theoretically, it could happen.


Ivan Martinovic of the University of Oxford and colleagues at the University of Geneva and University of California at Berkeley describe research into that question in a paper entitled "On the Feasibility of Side-Channel Attacks With Brain-Computer Interfaces" presented earlier this month at the 21st USENIX Security Symposium.
The research was inspired by the growing number of games and other mind apps available for low-cost consumer EEG devices such as Emotiv's EPOC headset, which lets users interact with computers using their thoughts alone.
Malicious developers could create a "brain spyware" app designed to trick users into thinking about sensitive information, which it would then steal.

ROBOTS CONTROLLED BY RAT NEURONS!!

These machines are being controlled by biological cells!!

Robots being controlled by rat brains. Kevin Warwick, once a cyborg and still a researcher in cybernetics at the University of Reading, has been working on creating neural networks that can control machines. He and his team have taken the brain cells from rats, cultured them, and used them as the guidance control circuit for simple wheeled robots. Electrical impulses from the bot enter the batch of neurons, and responses from the cells are turned into commands for the device. The cells can form new connections, making the system a true learning machine. Warwick hasn’t released any new videos of the rat brain robot for the past few years, but the three older clips we have for you below are still awesome. He and his competitors continue to move this technology forward – animal cyborgs are real.So we can think of our future
Bus and other transportations thinking of its own and drives the vehicle through signals.So without programming they can think of their own and make decisions like us.It is only one example think of your own what would happen in our future.

 

HAVE FUN BY PRINTSCREEN BUTTON.....

SIMPLE BUT FUN

You know the use of Print screen button on the keyboard [present on top right above insert or delete] .
Print Screen is a command key you see on the keyboard that is labeled as Prnt Scrn, Prt Scn, Prt Scr or Prt Sc
It captures the screen , right ?
But now I will tell you how to use it for some fun .
Take a screenshot of the desktop by pressing Print Screen on the desktop .
Go to Paint and paste this .
Save it .

For Windows 7 users
1) On the desktop right click -->view---> De-select 'Show Desktop Icons '

For Windows XP users
1) On the desktop right click -----> arrange icons by ----> De-select 'Show Desktop Icons '.

Remaining same for xp and windows 7
2) Now right click the taskbar and select properties .
3) Check auto hide the taskbar. Click OK.
4) Now change your wallpaper and keep the one you saved earlier.
5) If paint is not closed, select File ---------> 'Set as background (Centered) '.
Now on the desktop even if you click any icon nothing will happen !!!
So Now do I need to tell you how you can use it for fun on someone else's PC ?

To revert back to normal change the wallpaper and select 'show desktop icons' on the right click menu .

DOES EVERYTHING IN UNIVERSE WE SEE IS REAL??

-->Is it true that the stars or other we see may not exist practically now but we still see them     on the sky?
-->Does stars ,moon etc we see in the universe are at not real with respect to time?
-->Is it true that the stars we see may be already dead?

Answer is yes..

Reality as  we sense it, is not quite real. The stars we see in the night sky, for instance, are not really there. They may have moved or even died by the time we get to see them. This unreality is due to the time it takes for light from the distant stars and galaxies to reach us. We know of this delay.It is explained below 

 For example a star  approximately 500 light years(light year is the distance travelled by the light in one year)  away from earth, so when we look at that star,light from the corresponding star travels 500 years and reaches to earth and then on our eye,so what we're actually seeing is what that star looked like 500 years ago!.That means we are seeing the light of star which is emitted 500 years ago!!.so the star may or may not exist or present at that point but its image of 500 years back.

 

Even the sun that we know so well is already eight minutes old by the time we see it.

So everything in universe we see is not in real time and its delayed with some time as light takes some time to travel.(Basic point is we can see an object only if light is projected on that object or emmitted from that object).

DIFFERENCE BETWEEN X64 AND X86

x86 refers to any processor that is instruction-compatible with the Intel 8086 and higher. This includes the Pentium, Pentium II, Celeron, Pentium III, Pentium 4, Pentium D, Core Duo, Core 2 Duo, Core i7, Atom, AMD Athlon, Sempron, Athlon 64, Phenom, and Geode. In summary 32 bit type processors

x64 is often used to refer to any x86 processor that has 64-bit extensions (x86-64). These include the AMD Athlon 64, late models of the Pentium 4, Pentium D, Core 2 Duo, Phenom, and certain Geode processors. In summary 64 bit type processors


x32 is a retcon of the x64 term to apply to either 32-bit only processors or programs.

Microsoft publishes KB946765 which details the main differences between 32-bit and 64-bit Windows Vista, which mainly relate to memory accessibility, memory management, and enhanced security features, as listed in table below.
Architecture Windows Vista, 32-bit versions Windows Vista, 64-bit versions
System requirements 1-gigahertz (GHz) 32-bit (x86) processor or 64-bit (x64) processor,
512 MB of RAM
1-GHz 64-bit (x64) processor, 1 GB of RAM (4 GB recommended)
Memory access A 32-bit version of Windows Vista can access up to 4 GB of RAM. A 64-bit version of Windows Vista can access from 1 GB of RAM to more than 128 GB of RAM.
Memory access per edition All 32-bit versions of Windows Vista can access up to 4 GB of RAM. Windows Vista Home Basic – 8 GB of RAM
Windows Vista Home Premium – 16 GB of RAM
Windows Vista Business – 128 GB of RAM or more
Windows Vista Enterprise – 128 GB of RAM or more
Windows Vista Ultimate – 128 GB of RAM or more
DEP 32-bit versions of Windows Vista use a software-based version of DEP. 64-bit versions of Windows Vista support hardware-backed DEP.
Kernel Patch Protection (PatchGuard) This feature is not available in 32-bit versions of Windows Vista. This feature is available in 64-bit versions of Windows Vista. Kernel Patch Protection helps prevent a malicious program from updating the Windows Vista kernel. This feature works by helping to prevent a kernel-mode driver from extending or replacing other kernel services. Also, this feature helps prevent third-party programs from updating (patching) any part of the kernel.
Driver signing Unsigned drivers may be used with 32-bit versions of Windows Vista. 64-bit versions of Windows Vista require that all device drivers be digitally signed by the developer.
32-bit driver support 32-bit versions of Windows Vista support 32-bit drivers that are designed for Windows Vista. 64-bit versions of Windows Vista do not support 32-bit device drivers.
16-bit program support 32-bit versions of Windows Vista support 16-bit programs, in part. 64-bit versions of Windows Vista do not support 16-bit programs.
