The First World War was one that led to numerous military developments between 1914 and 1918. Chemical weapons were used extensively. The idea had already existed and had been considered in other conflicts before, but it was really the first global conflict that brought it to fruition.
It's important to understand that assaults were infrequent, with the sides generally in trenches. To push the enemy back a little, the use of gas on both sides began to multiply. It was during the attack on Ypres, Belgium, on April 22, 1915, that the first mass gas offensive was carried out by the German block with chlorine gas. Tens of thousands were poisoned, and 1,000 died, forcing the Germans to give way.
From this date onwards, both sides produced progressively more dangerous gases to attack each other, including the well-known mustard gas, so named because its odor was somewhat reminiscent of the plant. Not surprisingly, each side tried to protect itself from attack. The first gas masks were mainly cloths soaked in various chemicals. Each side went on to develop increasingly elaborate masks, taking advantage of the opportunity to apply them to the animals used on the battlefield. The gases themselves were not so lethal. According to some sources, 93% of affected soldiers were able to return to combat. Nonetheless, the long-term effects on health were sometimes very harmful.
Many years later, these masks are less common during conflicts, but they are still used by firefighters, sanitation workers and others who need to protect their lungs from various harmful products.

Trust at the heart of remote success
There are many elements that lead to a learner's success. Nevertheless, trust is of paramount importance. Even more so in a remote context where the learner cannot count on the physical presence of the teacher. Moreover, the teacher must also believe in his or her abilities when it comes to teaching online.

Can AI serve collective intelligence?
AI can better serve human interests provided it is socially supervised and its users are educated about its effects.
The question of humanity's place in a digital world is constantly being asked, and ironically, the world of live performance could very well use technology to show people about contemporary and future issues. Of course, ideally, creation would remain in the hands of humans, not machines; audiences will generally prefer sensitivity to the coldness of an algorithm.
How can universal design for learning be applied?
Access to learning is supposed to be a universal right. In reality, however, schools reproduce, whether unconsciously or not, biases and divisions based on various criteria such as socio-economic background, gender, ethnic origin, etc. Can we introduce an inclusive pedagogy for all students? Is it possible to introduce an inclusive pedagogy for all students?
