Indian American developing infrared super computers

Washington: A computer that is a thousand-fold faster than the fastest current supercomputers is being developed by an Indian American scientist.

The machine of the future being developed by Ashok Nahata of the University of Utah relies on infrared wavelengths rather than electrical wires.

Nahata and his team made the equivalent of wires that carried and bent this form of infrared light, or terahertz radiation, the least exploited segment of electromagnetic spectrum.

Scientists want to harness this spectrum, since vast loads of communication clog the existing spectrum. It would not only make for much faster computing but also help in designing scanners and sensors able to detect biological, chemical or other weapons.

Nahata said the long-term goal is to develop capabilities to create circuits that run faster than modern-day electronic circuits "so we can have faster computers and faster data transfer via the Internet".

"We have taken a first step to making circuits that can harness or guide terahertz or infrared radiation," said Nahata. "Eventually - in a minimum of 10 years - this will allow the development of superfast circuits, computers and communications."
The findings will be published Friday in the online journal Optics Express.

Navigating the JOBS in the times of AI

One of last staturdays I spoke to first-year students on the opening day of their year. Eighteen, most of them. Some had come for computer science, some for the humanities, some for management or commerce or the pure sciences. Bright, a little restless, and all of them carrying the same question without quite saying it: now that AI has shown up, what happens to my career? I want to write down what I told them, because I don't think it's a question only eighteen-year-olds are asking. Why do jobs even exist? Strip everything away and a job is just a problem somebody is paid to solve. People need food, health, a roof, education, safety, someone to talk to. Those needs don't go anywhere, and every one of them is somebody's work. What's easy to miss is that the needs stay put while the way we meet them gets rewritten every couple of generations. Farming gave us a food surplus. The steam engine gave us factories. Electricity, mass production. Computers, the information...

आपण महाराष्ट्राच्या संस्कृतीचे अजूनही खरंच पाईक आहोत कि भरकटलोत ?

महाराष्ट्र दिनाच्या सगळ्यांना शुभेच्छा. तसं ज्याला आज आपण महाराष्ट्र म्हणतो, त्याचा हा आधुनिक जन्म दिवस. महाराष्ट्र कधी पासून अस्तित्वात असेल? म्हणजे इथली संस्कृती, आपण जे वागतो, जगतो, बोलतो, राहतो वगैरे वगैरे. कधी पासून हे सगळं असं असावं? याचं उत्तर आपल्या सारख्या सामान्यांपेक्षा हा ज्या कोणत्या विषयाचा विषय असेल त्या विषयाच्या निष्णातांना जास्त चांगलं माहित असेल. तरी, आपला एक सामान्य माणूस म्हणून या भूमीवर अधिकार आहे आणि त्याच अधिकाराने आपण आपला एक अंदाज लावू शकतो. म्हणजे ज्ञानेश्वर-नामदेव इथे आपल्याला या मराठी राज्याची - महाराष्ट्राची - सुरुवात झाली असावी, असा अंदाज लावता येईल.म्हणजे आजच्या आपल्या मराठी म्हणता येईल अशा संस्कृतीची सुरवात तिथून झाली असं आपण समजू शकतो. किंवा मला जे मांडायचं त्या साठी ते सोयीचं आहे म्हणून समजा हवं तर! पण मीच कशाला वारकरी साहित्यातच संत बहिणाबाईंनी लिहून ठेवलयं - संतकृपा झाली । इमारत फळा आली ॥ १ ॥ ज्ञानदेवें रचिला पाया । उभारिलें देवालया ॥ २ ॥ नामा तयाचा किंकर । तेणें रचिलें तें आवार ॥ ३ ॥ जनार्दन एकनाथ । खांब दिधला भागवत ॥ ४ ॥ तुका झालासे कळस । भजन करा ...

NVDIA AI India

NVDIA AI some Insights after digesting the event with some Diwali Delicacies! I had good time at the NVIDIA AI Summit held at the Jio World Center in Mumbai. It felt like every company working on artificial intelligence in India was present, either as an exhibitor or an attendee. Some sessions were so packed that people were standing, and even then, many more were trying to get in. Much of the discussion revolved around Large Language Models (LLMs) and Retrieval-Augmented Generation (RAG). These are undoubtedly central topics in AI today, drawing significant attention. I’m a huge admirer of RAG, but I still wouldn’t go as far as to say that “LLM (+RAG) is AI.” Although no one at the conference explicitly said this, it felt implied over the three days of sessions. I may be wrong, but I sensed a push for these technologies. Not just from NVIDIA, but from any hardware supplier, there’s an incentive to promote anything that drives demand for their solutions. NVIDIA’s GPUs are a backbo...
