Marine energy (also referred to as marine power, ocean energy, ocean power) refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences. The movement of water in the world’s oceans creates a vast store of kinetic energy or energy in motion. Some of its energy can be harnessed to generate electricity to power homes, transport, and industries.
The term marine energy encompasses both wave power i.e. power from surface waves, and tidal power i.e. obtained from the kinetic energy of large bodies of moving water. …
Maybe not everyone knows what quantum physics is. A much debated, fascinating, and capable of revolutionizing the idea we have of the universe that surrounds us. Some have embraced quantum discoveries as a way of seeing existence. So what is behind this relatively new discipline? Let’s find out together by retracing the main stages and insights of innovative science.
It is known as quantum physics but it can also be called quantum theory\ mechanics. …
Working with dates holds very unwelcome surprises due to the different formats they can take. In this short article, we will see how to choose the format we prefer, thanks to the Python pandas library.
Here we are grappling with the age-old question: European or American format? When we write 02/03/2010 do we want to indicate March 2nd or February 3rd?
Unlike what happens in Excel, the format of dates in pandas does not depend on the geolocation settings of our device, but it is something that we can specify from time to time.
Let’s imagine we have the following…
When we generate a dataframe or import a dataset with pandas, it automatically creates a column that acts as an “index”. In this short article, we will see together how to attribute the index function to another column (or to more columns) and above all what are the advantages of this operation.
Let’s take a simple example by importing a CSV file into pandas that contain a list of some people with their data. Our data set looks like this:
A phenomenon through which matter can be generated directly only with light was demonstrated in an important experiment conducted by a team of scientists who used the Relativistic Heavy Ion Collider (RHIC), an accelerator of the Department of Energy. of the United States located at Brookhaven National Laboratory.
The Relativistic Heavy Ion Collider (RHIC) is a world-class particle accelerator at Brookhaven National Laboratory where physicists are exploring the most fundamental forces and properties of matter and the early universe. With this accelerator, researchers are able to accelerate gold ions to 99.995% of the speed of light. As explained by Zhangbu…
Let’s imagine we have a data frame called df and don’t know if it contains null values. We can check immediately with the command df.isnull().
print ( df.isnull() )
we will see a version of our data-frame similar to the following:
Water is extremely present on the Earth’s surface and is considered the renewable resource for excellence: it is used in food, sanitation, but also in production processes concerning a large number of sectors. Despite this, its deposits are not distributed evenly across the planet and are not accessible in all areas. This generates serious inequalities to which are added pollution problems originating from industry or poor sanitary conditions.
Chinese artificial sun beats the Korean one by 60 million degrees.
It is called ‘artificial sun’ and actually, a more appropriate nickname could not exist: the Korea Superconducting Tokamak Advanced Research (KSTAR) broke all records, maintaining the temperature of 100 million degrees for 20 seconds.
The KSTAR is an advanced research device on magnetic nuclear fusion, built at the National Fusion Research Institute in Daejeon, South Korea. With the aim of studying the possibility of obtaining magnetic fusion energy, it was approved in 1995 but has delays due to the East Asian financial crisis which has significantly weakened the South…
Among the large amount of waste that is produced every day, particular attention must be paid to the component of electronic waste. The latter, in fact, represent one of the highest percentages of waste that human beings produce in the world and, often, they are non-recoverable disused electronic devices that end up in landfills.
A considerable share of electronic waste is also represented by screens, which are very difficult to recycle. Thus a group of scientists has well thought of solving at least part of the problem of electronic waste by producing an innovative display built with biodegradable materials. …
I’m not talking about converting water into steam or burning gas to rotate electric generators. Those days were over I believe. I’m talking about “Thermo Electric Generators”. Okay, now What is this Thermo Electric Generator?
Thermoelectric generators (TEG) are solid-state semiconductor devices that convert a temperature difference and heat flow into a useful DC power source. Thermoelectric generator semiconductor devices utilize the Seebeck effect to generate a voltage. This generated voltage drives electrical current and produces useful power at a load.
