A banner for an educational event called 'Semaine de l'Esprit Critique' (Week of Critical Thinking). The design should be vibrant and engaging, aimed at a young, student audience. Include elements that represent critical thinking, such as a brain with gears, magnifying glass, and open books. Incorporate a diverse group of cartoon-style students, some holding scientific equipment like a telescope, microscope, and beakers, others with books and pens. The event dates '2 - 9 April 2024' should be prominently displayed, along with the email contact 'profcudelmaths@gmail.com'. The background should be colorful and dynamic, suggesting creativity and intellectual curiosity.  --ar 851:315
