Does Hot Water Really Freeze Faster Than Cold Water?

Does hot water freeze faster than cold water?

This phenomenon, which seems completely illogical, was already observed by Aristotle himself. He noted that some inhabitants of present-day Turkey sprinkled the stakes of their palisades with hot water to safeguard them. Apparently, they did so because that way they froze faster. Francis Bacon and René Descartes also took note of this physics curiosity. Yet,… Continue reading Does Hot Water Really Freeze Faster Than Cold Water?

Highest and Lowest Temperature in the Universe?

Highest and Lowest Temperature in the Universe.

We will start by explaining the physical phenomenon on which the temperature that something can have depends. When the particles of an object move a lot, they generate heat, and the entity has a higher temperature. When particles move less, there is less heat, and the thing is colder. We can imagine a point where… Continue reading Highest and Lowest Temperature in the Universe?

What Is the Farthest Thing That Can Be Seen With the Naked Eye

Farthest Naked Eye Object.

You surely expect that now we will go about explaining what a tangent is, how human sight works and how we calculate the distance to the horizon. But no. We all know perfectly well that the most distant objects that can be seen with the naked eye have to be in space. In that case,… Continue reading What Is the Farthest Thing That Can Be Seen With the Naked Eye

Researchers Created the First Map of Bee Species Around the World

According to scientists, their study will improve understanding of the world's diversity of bees and contribute to their preservation throughout the planet.

When it comes to bees, many people think of the honey bee and maybe also the bumblebee. According to scientists, there are more species of bees than birds and mammals combined. Researchers from China, the USA and Singapore have now created the first map showing all bee species worldwide. The map was published on November… Continue reading Researchers Created the First Map of Bee Species Around the World

5 Important Questions About Phytonutrients and Their Benefits

What are Phytonutrients?

Phytonutrients is a term from the science of nutrition. As you can see from its shape, phytonutrients are nutrients that are found in plants. The phytonutrients have many different functions. Above all, they protect plants from bad environmental conditions and pests. Outside plants (for example, in the body of a person who eats vegetables), these… Continue reading 5 Important Questions About Phytonutrients and Their Benefits

What are pandoraviruses and why some scientists doubt they are actually viruses

Pandoraviruses.

When the first pandoravirus was described a few years ago, scientists were clear that they were dealing with something unprecedented. Pandoraviruses are part of the family of giant viruses and can be up to 10 times larger than a common virus, even measuring as much or more than other small bacteria. In addition, they have… Continue reading What are pandoraviruses and why some scientists doubt they are actually viruses
