Science exploration should be used as a tool to understand the nature, where the outcomes are reliable in sustaining the natural balance and accordingly safeguarding the rights of all. Scientists should limit themselves from redefining the existing natural algorithms and variables within it, and from compromising the high appreciation and respect to other organisms that coexist on this earth. Science should not be used to underestimate the complex nature of the ecosystem for the benefits of very few. --Ahmad Fairuz Omar-- War is a single man-made event that will completely annihilate the entire 17 Sustainable Development Goals. To ensure the ongoing efforts are realistic rather than mere rhetoric, the world governance should mutually condemn the pathetic and despicable history of wars and those who continuously beating the drums of war throughout the modern century; and at the same time pledge that the only path to peace is through peace. Civilisation can only exist and prevail in the mature society that can effectively inhibit conflict. --Ahmad Fairuz Omar-- The wealthy are driving and monopolizing the direction of humanity through the scientific data and the integration of technology in everyday life; while the best of the rest and their followers remains fighting to stand on their arbitrary philosophical ground; and the rest of mankind are struggling to understand and compromise their basic necessities. --Ahmad Fairuz Omar-- It has come to my attention that many recent papers submitted on sensing and its integration with machine learning has almost completely abandoned the discussion on sensing mechanism in relation to the samples properties, which should have been the core scientific element in the research paper. --Ahmad Fairuz Omar-- The only thing that I may regret in my entire life, is the failure to establish proportionality between time spent and knowledge gained. --Ahmad Fairuz Omar-- RESEARCH INTEREST The application of ultraviolet, visible and near infrared (aquaphotomics) spectroscopy, colorimetry, optical fiber sensor technologies and the development of specialized / simplified optical sensing system for: https://scholar.google.com/citations?user=DoAIjGMAAAAJ&hl=en&oi=ao My Current Research Works Optical Characterization of Water Qualities In collaboration with Dr. Norizham Abdul Razak (School of Aerospace Engineering) Spectroscopic Quantitative Analysis of Fruits Qualities: Taste is in the eye of Beholder?

He should also suspect himself as he performs his critical examination of it, so that he may avoid falling into either prejudice or leniency” Abū ʿAlī al-Ḥasan ibn al-Ḥasan ibn al-Haytham.
