Despite the aesthetic differences between these two, their exchange was one of warmth and understanding
The Differences Board, an exact recreation of the one used in the First Episode of Season Two of Derry Girls.
This photo was taken October 5th at Clagett Farm in Upper Marlboro, Maryland. This demonstration allows visitors to visualize the difference in runoff and infiltration between permeable pavement, concrete, till non-cover crop, and cover crop. The jars in the back represent infiltration while the jars in the front represent runoff. For the tilled, non-cover crop soil, the runoff is greater than the infiltration. For the cover crop, the infiltration is much greater than the runoff. For the concrete, the runoff is greater than the infiltration. For the permeable pavement, the infiltration is greater than the runoff. This setup demonstrates how different types of soil treatments/urban planning affect sustainability. Tilled soil is generally unsustainable because tilling disrupts soil structure and causes compaction, resulting in decreased infiltration and more runoff. Agricultural runoff negatively affects the environment by carrying with it pollutants such as fertilizer (nutrients), pesticides, and bacteria. Cover crops, however, enhance organic matter and pore space, causing better infiltration and reducing environmental impacts from runoff. Finally, permeable pavement limits flooding from stormwater by allowing infiltration as opposed to concrete.
This photo depicts the ecological concept of human impacts on soil properties and processes. As we discussed in class, urban soils are often highly disturbed due to human activity. This is true for many agricultural soils as well. Specifically, tilling strongly affects the soil profile by disrupting soil structure, leaving soils susceptible to rain and subject to large amounts of soil loss and runoff. Tillage also alters soil structure by diminishing organic matter. We also discussed soil’s numerous physical properties in class. One of these is compaction, which tilling can cause by destroying active organic matter (causing less pore structure created by soil life), and by heavy equipment pushing soil microaggregates together (Hoorman et al., 2011). Finally, we also discussed how soils can develop through losses. Tilled soils are susceptible to nitrate leaching and nutrient loss (Lv et al., 2023).
This photo relates to UN SDG 6-Clean Water and Sanitation. This sustainable development goals aims to ensure access to safe and affordable drinking water and sanitation. Water pollution from agricultural runoff is capable of degrading the quality of drinking water. According to the EPA, pollution from pesticides, fertilizers, and animal manure can enter groundwater and degrade sources of drinking water depending on the local geologic conditions and land use (EPA, 2024). As demonstrated by the image, farmers can take action to reduce their impact on water quality by incorporating reduced till/no-till methods and cover crops to limit runoff. The ecological principle and SDG are closely related. Soil properties and water filtration and efficiency are intertwined. Healthy soil that is strong in structure and high in organic matter has better infiltration and experiences less losses, preventing water contamination and contributing to Target 6.3, which aims to improve water quality by reducing pollution. This also limits pollution to water-related ecosystems, contributing to target 6.6. Practices that enhance organic matter and structure, such as no-till and crop rotation, improve water infiltration and retention, reducing the demand for irrigation and causing increased water efficiency in agriculture.This is critical for target 6.4 which aims to enhance water-use efficiency and “ensure sustainable withdrawals of freshwater to address water scarcity” (United Nations).

The difference bewteen the recorder photographer... and the artist photographer... is that the artist will, by experience and learning... force the camera to paint the imagination...the emotion... the concept and the intent... rather than faithfully and truthfully reproduce an unnatractive and unflattering record.

They might look like subtle differences on the outside but not in performance. These are F1 tyres produced by Pirelli. On the left is the red tyre. It is the softest compound and reaches temperature the quickest with the advantage of grip but at a cost of durability. On the right the white tyre which is the hardest compound and offers durability over longer distances. In the middle is the yellow tyre, its compound falls between the other two and it combines speed with durability.
Seen at the F1 exhibition at Excel, London.

What a difference a few days can make in the life cycle of a fire. In this particular case, the Thomas Fire that is ongoing in the Ventura County around (and surrounding) in Southern California. The following images were taken by the Terra and Aqua satellites on Dec. 16, 17, and 19, 2017, and during those times fire conditions improved visibly. A difference in winds, in humidity, in the ability of firefighters to control the fire's perimeter, and in the amount of fuel left for the fire to consume can bring a raging fire to heel. This does not mean the fire cannot gain strength again if conditions worsen, but it is heartening to realize that weather conditions can allow firefighters to get a better handle on events as they have in the last few days.

A website is a collection of web pages that are interconnected by hyperlinks and hosted on a server accessible over the internet. Websites are primarily designed for presenting content in a static format to users. They provide information on various topics, promote businesses, and offer services such as e-commerce, blogging, and news. On the other hand, a web application is a dynamic software program that runs on a web server and provides a more interactive and engaging experience for users. Web applications allow users to interact with the website and perform specific tasks, such as filling out forms, making reservations, and purchasing products. Unlike websites, web applications are more complex and require more advanced technologies to operate. They are designed to meet specific user needs and typically offer a personalized experience. We hope now you understand the difference between website and web application.
