What is a degree

What is a degree?

A degree is a unit used to measure temperatures. You can express it in °C,K or °F

The fahrenheit scale was created by Daniel Gabriel Fahrenheit in the 18th century. During his studies in Poland, he decided to create a temperature scale based on the blood temperature in the human body: he chose 98.6°F he then added more temperatures such as; the melting point of ice(32°F)and the boiling point of the water(212°F)

After The French Revolution at the end of the 18th century,a lot of countries changed their temperature scale from Fahrenheit to Celsius since it was a lot more easier. Indeed, in celsius the freezing point of water is 0°C and the boiling point of water is 100°C

Finally, Lord Kelvin invented the Kelvin scale which is now the most used temperature scale in the world

Those scales give us formules:

C=(F-32)*5/9 ; F=(C*5/9)+32

0°C=32°F 0°F=-18°C 0 K=-273°C

100°C=212°F 98.6°F=37°C

-40°C=40°F

What is a degree

The degree is a unit to measure the temperature

There is 3 types of degree used in the world

-The Celcius (the most used in the world)

-The Farenheit (used in USA)

-The Kelvin (international system)

Gabriel Farenheit created the scale of farenheit during the 18th century

Boiling temp of water : 100°C / 373°K/212°F

Freezing temp of water : 0°C/273°K/32°F

What is a degree?

A degre can be in three different units : the Fahrenheit in F, the Kelvin in K and the Celsius in C. The boiling point of water is at 100°C so in Fahrenheit it's at 212°C. Daniel Gabriel Fahrenheit base on the tempeture of the blood. That units are create in the 18e century.

We have three different formula:

Form the Celsius to the Fahrenheit :C=(F-32)*5/9
Form the Fahrenheit to the Celsius: F=(C*9/5)+32
Form the Celsius to the Kelvin: K=C+273
Form the Kelvin to the Celsius: C=K-273

The maga flash lightning

A new world lightning record was set in the United States with a bolt nicknamed the "megaflash," stretching an incredible 768 kilometers. This exceptional phenomenon crossed the states of Texas, Louisiana, and Mississippi in 2022, but its measurement was officially confirmed in 2024 by the World Meteorological Organization (WMO).
This colossal flash surpassed the previous record of 709 km, set in Brazil in 2018. Contrary to popular belief, this type of lightning is not vertical but horizontal, spreading between clouds.
The event caused no damage or injuries, but it is impressive due to its sheer scale.
This megaflash highlights the extreme power of thunderstorms and the importance of weather monitoring.
Scientists use specialized satellites to detect these rare events. This record underscores the technological progress made in understanding atmospheric phenomena.

10 FACTS ABOUT SPHERE X

1. The SPHEREx space telescope will shed light on a cosmic phenomenon called inflation.

2. The observatory will measure the collective glow from galaxies near and far.

3. The mission will search the Milky Way galaxy for essential building blocks of life.

4. It adds unique strengths to NASA’s fleet of space telescopes.

5. The SPHEREx observatory will make the most colorful all-sky map ever.

6. The spacecraft’s cone-shaped design helps it stay cold and see faint objects.

7.It will collect data on more than 450 million galaxies and more than 100 million stars in the Milky Way.

8.This satellite will scan the sky in visible light and near-infrared to determine the composition of young stars and their protoplanetary rings.

9.SPHEREx will specifically target the stellar nurseries in our galaxy, which give birth to new stars.

10.It will also involve determining the position of galaxies in the distant Universe, and cross-referencing this set of data to better understand the Big Bang.

JULY 2025:The third hottest july month ever

Diego and Manon

In July 2025, the global average temperature was 16.68 degree Celsius which is the third warmest July ever recorded, after 2023 and 2024. Many countries all around the world also reached new record temperatures. For exemple, Turkey recorded a temperature of 50.5 degrees Celsius, the highest temperature ever measured in the country. Other regions faced similar extreme heat;, showing that this problem is global. Even if this month ended the series of new world records, it doesn't mean that climate change is over. The very high temperatures had serious effects, such as large forest fires, floods and other extreme weather events. These events show us that climate change continues and will have dangerous consequences for people and the environment.
