Science & Technology   

Most technology headaches, security risks, costs, and electronic waste are preventable. This course explains the IT industry in plain English, including a look at recent trends such as the Windows 11 cash grab. Participants will learn the core components of computers and tablets, why traditional antivirus software is largely obsolete, and the four major modern threats. The course also covers proper backup practices, avoiding fake rental Wi-Fi, how to extend a computer’s lifespan to up to 15 years, ways to save money on printing, and includes time for questions.

In this class, with ASU's Dr. Ken Sweat, we will examine the use of plants and other organisms, such as algae and fungi traditionally grouped with plants, as evidence in criminal investigations. Starting with the wood grain of the ladder left at the Lindbergh residence and continuing into modern genetic techniques, we will review how plant evidence has been in the past and can be expected in the future to help solve crimes, prosecute the guilty, and free the innocent.

When you or your family members decide how to spend your limited budget of time and money every day, are your choices rational or irrational? Classical economists assumed that we make well-informed decisions, rationally designed to optimally maximize benefits. Behavioral economists amassed data suggesting our decisions are often shockingly irrational and oversimplified. Evolutionary psychologists suggest a third view—that our decisions are neither ultra-rational nor fecklessly irrational. Please join Dr. Douglas Kenrick, President’s Professor of Psychology at Arizona State University, to learn more about how evolution made us smarter than we think.

Stress is gaining increased attention across the U.S. and globally due to its significant impact on physical and mental health. At the same time, mindfulness is emerging as a powerful, evidence-based tool for well-being, demonstrating how the simple act of self-awareness can help downregulate the body’s stress response, leading to a healthier and more fulfilling life. This presentation explores the neurobiology of stress and its effects on the brain and body, the science of neuroplasticity and our ability to rewire thought patterns, and practical, data-driven techniques to regulate the nervous system in the face of everyday and high-stakes stressors. With a dynamic blend of science, humor, and real-world application, this session will leave you thinking differently about stress, and empowered to lead your life with greater clarity, calm, and purpose.

In this course, we will explore a wide range of horticultural practices with something to offer no matter our experience level or where we live. We will cover container gardening, aquatic gardens, ornamental and fruiting plants, bonsai, landscape design, and pest management. Each week, we will focus on a theme and examine design ideas, plant choices, and long-term care practices for success. Whether we garden on 10 acres or in an apartment, we will find plenty to learn and enjoy in horticulture.

The music we stream, the photos we swipe through, the real time news we consume, the books we read or listen to – all have been radically reshaped by digital technology. This course will explore how media is created, stored, and experienced in a digitized world. We will unpack fundamentals like text files, encoding and decoding, pixels, and algorithms in clear, easy-to-understand ways – no prior computer knowledge needed. Each session will focus on a different medium, comparing its analog origins with its contemporary digital version. We will also consider the impact of Generative AI and speculate on future trends. Topics will include text (books, e-books, news portals), images (photography and movies), music, video games, social media, and media ownership (physical media, streaming, and copyrights).

This course will arm us with the knowledge we need to keep ourselves and our loved ones safe when engaging with the healthcare system. Health care today is more complex, technical, and volatile than ever. Medical harm (unintentional but often preventable) injures and kills hundreds of thousands of patients each year. In this course, we will learn how to prevent the most common types of medical harm including medication errors, patient care accidents, procedural and surgical complications, infections, and diagnostic mistakes. Patient safety experts and advocates will provide us with practical tips and insights to navigate the healthcare system confidently and safely. Through presentations, videos, and group discussions, we will come to understand the common sources of error and discover tactics, resources, and cautions to help protect ourselves and our loved ones.

Join Dr. Hendrickson (an erstwhile quantum mechanic) for a journey into the strange world of quantum physics. This branch of modern physics focuses on light and very small particles, which behave very differently from familiar, macroscopic objects. This is not a class in metaphysics (the philosophical study of time and space) nor will we cover quantum mechanics, the mathematical, how-to side of quantum theory. Instead, we’ll be tourists admiring the view, with no prerequisite knowledge of physics or math required. Please note that parking is the responsibility of the member. 

This class will introduce you to basic foundational skills in establishing a composition for a photo, using the rule of thirds, and considering the values in a photo. This content will be followed by an introduction to the many photo editing tools available on an iPhone and how to use them with the photos you have taken. If you have taken this class previously, you are welcome to take it as a refresher.

This class is brought to you by OLLI at Chico State University.
