What is Fabric of Spacetime ?

Spacetime, it is mathematical model which fuses the three dimension of space and one dimension of time. Classical mechanics treats time as universal quantity which is uniform throughout the space. Everything with this spacetime move along the path which is defined as curvature. Gravity is a first fundamental force but now also it is least understood. After the Theory of Special Relativity, it become easy to understood space and time are same entity. The presence of mass and energy curve space time and make it fabric. Therefore another object travelling through this fabric get bent dye to the gravitational source. This is the cause which explain expanding of universe or called stretching of spacetime.

But still the knowledge is incomplete because our less knowledge in Quantum Physics. When large masses move suddenly, some of this space-time curvature ripples outward, spreading in much the way as ripples on the surface of an agitated pond. When two dense objects such as neutron stars or black holes orbit each other, space-time is stirred by their motion and gravitational energy ripples throughout the universe in a manner represented by the picture at lower right.

SCADA Network

So welcome to my blog. In this post I am gonna write about SCADA network. This actually come to my mind because of web show named Mr. Robot. The show is awesome if you love hacking believe me you will enjoy the series. So basically the SCADA ( Supervisory Control and Data Acquisition ) is a control system architecture comprising computers, networked data communications and graphical user interface for high level process supervisory management, while also comprising other peripheral devices like programmable logic controllers and discrete proportional-integral-derivative controllers to interface with process plant or machinery. SCADA networks used for monitoring and controlling the industry like telecommunication, water plant, etc. It is one of the most commonly used industrial control system, in spite of concerns about SCADA system being vulnerable to cyberattack. This network is used for gathering info about the system, transferring that info to central site, alerting...

NVIDIA Tesla V100 - First Tensor Core GPU

8x NVIDIA Tesla V100 32GB Server As we all know NVIDIA processor are so famous now a days. It give a perfect gaming performance and people used it worldwide. The thing is that it is not only use in personal computer but also at data center, where so many super computer are present for providing services. So, NVIDIA Tesla V100 is a first tensor core GPU. It is especially built to focus on AI, High Performance Computing ( HPC ) and graphics. It is powered by NVIDIA Volta Architecture. It comes with configuration 16 and 32GB and have a performance up to 100 CPUs in single GPU. A single server node with V100 GPUs can replace 60 CPUs nodes. DATA CENTER GPUs Image © NVIDIA NVIDIA V100 for NVLINK Performance with NVIDIA GPU Boost for double precision is 7.8 teraflops and single precision is 15.7 teraflops. Deep learning performance boost is 125 teraflops. Interconnect bandwidth with bidirectional is 300 GB/s. It have memory capacity of 32/16 GB HBM2 with bandwidth 900GB/s. I...

The Amazing Vantablack Material...!!

Vantablack is a material developed by Surrey NanoSystems in the United Kingdom and is one of the darkest substances known, absorbing up to 99.96% of visible light (at 663 nm if the light is perpendicular to the material).The name is a compound of the acronym VANTA (vertically aligned carbon nanotube arrays) and the color black. Vantablack is not actually a color pigment or a paint, but a coating of carbon nanotubes. These have the property of absorbing incident light almost completely. Against a deep black background, objects coated in Vantablack material seem to disappear, as the perception of spatial depth is lost. This is because the human eye perceives shapes coated in Vantablack to be two-dimensional. IUPAC Name is Activated carbon high density skeleton. Other names are Multiwalled carbon nanotube (MWCNT), Vantablack S-VIS and Vantablack S-IR. It is insoluble in water. When light strikes Vantablack, instead of bouncing off, it becomes trapped and is continually deflected amo...
