Summary: ChatGPT4 has demonstrated superiority in various student exams, revealing its potential to support academic learning and improve educational outcomes, particularly in test preparation. With its accessibility and affordability compared to traditional tutoring services, AI tutoring can help address the increasing demand for academic support, especially as universities begin to reinstate standardized testing requirements.
In 2023, OpenAI shook the foundation of the education system by releasing ChatGPT4. The previous model of ChatGPT had already disrupted classrooms K–12 and beyond by offering a free academic tool capable of writing essays and answering exam questions. Teachers struggled with the idea that widely accessible artificial intelligence (AI) technology could meet the demands of most traditional classroom work and academic skills. GPT3.5 was far from perfect, though, and lacked creativity, nuance, and reliability. However, reports showed that GPT4 could score better than 90 percent of participants on the bar exam, LSAT, SAT reading and writing and math, and several Advanced Placement (AP) exams. This showed a significant improvement from GPT3.5, which struggled to score as well as 50 percent of participants.
This marked a major shift in the role of AI, from it being an easy way out of busy work to a tool that could improve your chances of getting into college. The US Department of Education published a report noting several areas where AI could support teacher instruction and student learning. Among the top examples was intelligent tutoring systems. Early models of these systems showed that an AI tutor could not only recognize when a student was right or wrong in a mathematical problem but also identify the steps a student took and guide them through an explanation of the process.
What is Control? here is a nice definition according to Wikipedia — Control engineering or control systems engineering is an engineering discipline that deals with control systems, applying control theory to design equipment and systems with desired behaviors in control environments. The discipline of controls overlaps and is usually taught along with electrical engineering and mechanical engineering at many institutions around the world. The practice uses sensors and detectors to measure the output performance of the process being controlled; these measurements are used to provide corrective feedback helping to achieve the desired performance. Systems designed to perform without requiring human input are called automatic control systems (such as cruise control for regulating the speed of a car).
The provincial government of Andhra Pradesh (AP) in India has entered into a Memorandum of Understanding (MoU) with the Gates Foundation to advance the use of technology in various sectors, including healthcare, agriculture, and education. The agreement was discussed in a meeting between AP Chief Minister N. Chandrababu Naidu and Bill Gates, the Foundation’s chair. Naidu reiterated his administration’s dedication to utilizing innovative technology to propel the state’s development.
The MoU focuses on applying technology in ways that will benefit the public, emphasizing affordable and scalable solutions across essential sectors such as healthcare, medical technology, education, and agriculture. According to Naidu, the collaboration will harness the power of artificial intelligence (AI) to enhance predictive health analytics and automate diagnostic processes. In the agricultural sector, AI-based platforms for expert guidance and satellite technology will be employed to optimize farming practices and resource management through precision agriculture techniques.
“This MoU formalises a strategic collaboration in which the Gates Foundation will provide support to implementation partners, co-identified with the AP government, for targeted interventions within state-driven programmes,” Naidu said.
“Tribhuvan” Sahkari University, through its innovative HUB-and-SPOKE model, will ensure nationwide reach and accessibility by integrating sectoral schools and leveraging strategic partnerships to build a robust Pan-India ecosystem of technical and skill development institutions.
To detect the quantum tornado in momentum space, the Würzburg team enhanced a well-known technique called ARPES (angle-resolved photoemission spectroscopy). “ARPES is a fundamental tool in experimental solid-state physics. It involves shining light on a material sample, extracting electrons, and measuring their energy and exit angle. This gives us a direct look at a material’s electronic structure in momentum space,” explains Ünzelmann. “By cleverly adapting this method, we were able to measure orbital angular momentum. I’ve been working with this approach since my dissertation.”
ARPES is rooted in the photoelectric effect, first described by Albert Einstein and taught in high school physics. Ünzelmann had already refined the method in 2021, gaining international recognition for detecting orbital monopoles in tantalum arsenide. Now, by integrating a form of quantum tomography, the team has taken the technique a step further to detect the quantum tornado — another major milestone. “We analyzed the sample layer by layer, similar to how medical tomography works. By stitching together individual images, we were able to reconstruct the three-dimensional structure of the orbital angular momentum and confirm that electrons form vortices in momentum space,” Ünzelmann explains.
This compares some of the ringworlds, centrifuges, space stations, and ships that use spin to make gravity. It also try’s to show how the variables of artificial gravity are used to make centripetal acceleration into spin gravity.

Artificial intelligence in various forms has been used in medicine for decades — but not like this. Experts predict that the adoption of large language models will reshape medicine. Some compare the potential impact with the decoding of the human genome, even the rise of the internet. The impact is expected to show up in doctor-patient interactions, physicians’ paperwork load, hospital and physician practice administration, medical research, and medical education.
Most of these effects are likely to be positive, increasing efficiency, reducing mistakes, easing the nationwide crunch in primary care, bringing data to bear more fully on decision-making, reducing administrative burdens, and creating space for longer, deeper person-to-person interactions.
