President Ram Nath Kovind greeted teachers across the country on the eve of Teachers’ Day on Friday. “With great pleasure, I extend my heartfelt greetings and felicitations to teachers throughout the country. We celebrate the Teachers’ Day on the birth anniversary of one of the greatest teachers of modern times and my illustrious predecessor, Dr. Sarvepalli Radhakrishnan,” Kovind said in a statement. He added that it is with sheer perseverance and patience that a teacher helps students comprehend the rich legacy of its culture.

Ideal teachers consistently encourage students to pursue this objective and realize their goals, the President said. “No doubt, teachers are the guiding force for students and true builders of our nation. This is the precise reason why the ‘Guru-Shishya’ tradition holds special reverence in Indian culture,” he stressed.

NOAA Office of Ocean Exploration and Research

Today’s technologies allow us to explore the ocean in increasingly systematic, scientific, and noninvasive ways. With continuing scientific and technological advances, our ability to observe the ocean environment and its resident creatures is beginning to catch up with our imaginations, expanding our understanding and appreciation of this still largely unexplored realm.

This section highlights some of the technologies that make exploration possible today and the scientific achievements that result from this exploration. Technologies include platforms such as vessels and submersibles, observing systems and sensors, communication technologies, and diving technologies that transport us across ocean waters and into the depths and allow us to scientifically examine, record, and analyze the mysteries of the ocean.

Researchers set a new world-record Internet speed

Researchers at University College London claim they’ve obtained a new top internet speed of 178Tbps – a fifth quicker than the prior record and fast enough to download the entire Netflix catalog in under a second, they say.

To achieve that, the researchers used different bandwidth ranges than are typically used in commercial optical systems. Traditional fiber infrastructure uses bandwidth of 4.5THz with 9THz becoming more available commercially. In UCL experiments, the scientists used 16.8THz.

To do this the researchers used a variety of amplifier technologies, customizing which ones they used for each wavelength to optimize its performance as measured by phase, brightness and polarization, according to a press statement put out by UCL. These customization packages are known as geometric signal constellations.

The amplifiers that they’ve been working with are called hybrid discrete Raman & rare-earth doped fiber amplifiers, and they used the S-, C—and L-bands simultaneously, according to
